Overview

Channel Master's 4228HD antenna can receive digital and analog over-the-air TV signals in the UHF band and high VHF band (nearly all digital TV signals are in the UHF or high-VHF bands). The 4228HD is optimized for "deep-fringe" reception of HDTV — it's one of the highest-gain antennas available.

KEEP READING

This antenna features a highly directional design that will provide best results when most or all of the desired stations are transmitting from the same location. For clearer reception, pair the 4228HD with the 7777 preamplifier — several Crutchfield employees are receiving digital stations from 50+ miles away with a similar setup. Also, if you'd like to pull in signals from different areas, consider a rotor to aim your antenna in the right direction.

The 4228HD is classified as a Large Directional antenna. Its space-efficient design is suitable for roof and attic installations (mast recommended).

Channel Master 4228

Product Research

Features

Overview: The Channel Master 4228HD antenna is designed for over-the-air broadcasts of UHF frequencies and high-band VHF frequencies (channels 7-13 and 14-69), both digital (HDTV) and analog. It can be mounted on a roof, on a wall, to a chimney, or in an attic. The antenna can be used with digital converter boxes or HDTV ready televisions.

Note: Many digital broadcasts still include non-HD content.

Construction: The Channel Master 4228HD antenna features a long lasting durable design with heavy duty aluminum elements and UV stabilized plastics.

Mounting Brackets: The mounting brackets and the U-bolt are used to mount the antenna to a traditional antenna mast (sold separately). The outer diameter of the mast should be approximately 1-1/4 inches.

Turning Radius: If using a rotor on the antenna mast, make sure a 20.5" turning radius around the antenna is clear of obstruction.

Grounding: The antenna and mast should be properly grounded. Grounding provides lightning protection for the antenna and your TV set.

Note: No grounding hardware is provided with the antenna.

Connections: The balun is built-in (attached at the factory) and has a female F-type connector. The included waterproof rubber weather boot should be installed over the cable connection to guard against corrosion. A twist-on threaded F-connector is also included.

Note: Coax cable is not provided, RG-6 is recommended.

Operating Range: The rated range of the 4228HD is up to 45 miles (channels 7-13) and up to 60 miles (channels 14-69), but the distance is approximate, actual performance depends on too many variables to predict accurately.

Gain: The average gain across the UHF frequency range is 12dB.

Will this unit improve FM reception on a home receiver? What's the best outdoor option to maximize FM and HD reception? Can 1 antenna do both properly, or better to use separate antennas and cables. (All transmitters in same general direction)

curtis Jul 02, 2019

metallic horizontal supports? Is this essentially two CM 4221's ganged together? Literature that i read says that horizontal connecting rods should be non-metallic. What are the connectors made of on the CM 4228? If metal, will they interfere with the signal reception?

richard Apr 17, 2018

3 answers

I've had mine since Dec.'16, works FANTASTIC with the pre-amp. No interference unless there is a significant weather event, it sometimes will "pixelate/freeze". When i say significant, typically heavy thundershower or dark blue heavy snow...other than that, perfect. Am considering purchasing a rotor as I can receive an additional 8 channels on the backside of the antennae. Mark M.-Central PA.

mark Apr 29, 2018

THe whole antenna is made of aluminum the cross braces don't seem to cause any problems. Sometimes station farther away from each other have trouble. Mainly channel 7 ABC in Chicago.

rick Apr 23, 2018

I've mounted the 4228 both on a metal pole and flat against a roof. I typically ground the mounting hardware with a ground wire and haven't had any issues with reception. I'm pretty sure that all the mounting structure is metal.

john Apr 23, 2018

will this work in the attic with a house with a metal roof?

richard Dec 31, 2016

1 answer

I get great reception with this antenna in the Attic up to around 80 miless. I'm not sure if the metal roof will affect the reception.

david Dec 31, 2016

What about VHF low-band reception? The technical specifications for this antenna are 174 to 216 and 470 to 700 MHz which translates AFAIK to channels 7-13 and 14-52.

johnl Apr 28, 2016

I have had no problem with this on low bands I get 2-52.

tim Apr 30, 2016

I don't really have an answer for that but as of 2009, only 2 percent of digital stations were in the low vhf range. Probably even less now. Overall I am happy with the antenna and amplifier I use. I summer at put in bay and get Cleveland and Toledo.stations very well.

charles Apr 29, 2016

JohnL: Your question is completely over my head. I can say that I installed the antenna inside my attic in Valparaiso and attempted to point the bowties towards South Bend. I (usually) recieve HD CBS, NBC, Fox, PBS, and several others from South Bend and the same from Chicago, adding HD ABC and many of what used to be UHF analog stations. HD reception from both cities degrades when it is raining or snowing. I am using an in-line amplifier per the advice of a man at Bowman Electronics in Valparaiso at the point where the Attic coax feeds into my house coax network. The HD picture is USUALLY solid and stable and certainly better than anything Comcast ever used to provide.

steven Apr 29, 2016

If mounted outside is it recommended to ground the coax shielding before running the cable in the house? Also can I split the signal to more TV's or is this recommended for only one?

steve Oct 25, 2015

2 answers

Splitting the signal works great. I just use a simple 3 way signal splitter/combiner and I spit it between a TV and 2 DVD Recorders. Works fine. I Cannot answer about putting it outside. I just put it on the wall inside the house and it works fine there. Reception all depends on where you are located, and what kind of interference is around your area.

brian Oct 27, 2015

The instructions that come with the antenna make no mention of grounding. If it was important, it would be stated there. I did not ground my coax. Then again, my antenna is mounted in the attic due to local code restrictions. What *is* important is to use a high quality coax. I used quad shielded RG6. It costs a little more, but for a one time investment, it's worth it. Whichever cable you choose, make sure it's 75 ohm impedance to match the antenna output. A good quality two-way splitter will reduce the signal strength by 3 dB to each TV set. That's the theoretical minimum loss. A 4 way splitter will lose 6 dB per outgoing signal. A low quality splitter will likely lose more signal. In an urban to near suburban area you probably won't be able to tell, especially with today's digital signals. But if you're in a more remote location and you need to feed the signal to multiple sets, consider inserting a good quality antenna amplifier, one where the amplifier itself is mounted just below the antenna. Finally, read the instructions and pay attention antenna placement, orientation and cable routing. Don't approach electrically noisy equipment such as air conditioners, etc. Finally, I'm very pleased with my 4228HD. It works great!

philip Oct 27, 2015

Would 75 ohm RG-6 coax work with this antenna?

scott Jun 29, 2015

3 answers

I purchased the QUAD SHIELDING cable, HUGE difference!

mark Apr 29, 2018

Yes, absolutely. The main thing to observe is the 75 ohm impedance. The antenna has 75 ohm output. You're good to go.

philip Jun 30, 2015

It has been a while since I've done this type of work, however I believe that RG-6 is suitable in this application.

jeffrey Jun 30, 2015

I am working out the logistics of using this antenna in my attic but my house is in a valley with a moderately wooded lot and we're located 20 miles from Milwaukee.. I understand that this antenna is L.O.S. will this work? Cheers Mark~ ~

gerald Feb 11, 2015

Hi Mark, I live in a wooded area outside of Boston and it has performed very well for me. Stations have better clarity than cable in many cases. You will be happy with the purchase. Regards, Rick

richard Feb 11, 2015

Honestly, it works as well as a good quality indoor antenna in any application

steven Feb 09, 2015

I have my antenna mounted outside and it works great.but in the attic i am not sure

roger Feb 08, 2015

I live approximately 35 miles west of Columbus, Ohio and 30 miles east of Dayton, Ohio, have this antenna in an upstairs bedroom window, with a signal booster. I am also down over a hill from both cities. I get all the channels offered over the air by both cities. I would say that this antenna will work for you.

william Feb 08, 2015

Mark I'd say that it's worth a try. My 4228HD is mounted outside on the end of my garage on a 10 foot mast so its probably 30ft off the ground. The signal I get is from over 40 miles away and obscured by trees. I get all of the local MSP digital channels with a picture that I say is better than the satellite signal DTV. I wish I had tried putting the antenna in the attic of my garage before I put it outside. I may be going that way as the mast is already slightly bent due to high winds. Good luck

regan Feb 08, 2015

Mark, I think you should be good if you are 20 miles from your transmitters in Milwaukee. By way of comparison, I am about 35 miles from the transmitters in Atlanta and I live in a bit of a hole, with a small hill behind my house that has trees on top of it. So, my antenna faces the hill and trees and does not clear the tops of the trees. With roof mounting, it does great even with the signal split between two different rooms without an amplifier. I have it roof mounted because of my positioning plus the range, but I tried it in the attic first. It got okay reception based upon my situation; you should get much better. So, if you are 20 miles away and not behind a hill, or at least have the antenna level with the top of the trees, I think it would be worth a shot. Check and see if any of your channels are VHF. The VHF ones are true los and will be more problematic if the signal has to go through trees. But, I think you will be good with this one. I would be interested to see if it works for you. -Steve

steve Feb 08, 2015

my attic has been converted into a bed room. If I put the atenna there do you think it's a health hazard me being in the same room?

yvonne Feb 04, 2015

4 answers

I think not - signals are all around you all day long - from cell phones, cordless phones, TV transmitters, radio transmitters, Wi-Fi and on and on. Stay clear of your microwave though.

regan Feb 08, 2015

No I don't think is a health hazard, providing you install the antenna outside of the room. Regards, Juan Somarriba

juan Feb 06, 2015

roger p Feb 05, 2015

No the HDTV signal is already traveling in the air and can't hurt you. This antenna uses no power and just picks up the HDTV signal in the air and sends it to your tv through the cable wire.

jim Feb 05, 2015

What are the dimensions? I have a small opening to get into my attic.

ken Jan 06, 2015

6 answers

according to the Crutchfield website it's about 3 ft X 4 ft

regan Jan 07, 2015

I do not recall exactly what the dimensions are but something like 3 x 36. If the opening is too small you could probably assemble it in the attic. Hope this helps. It is doing a great job of pulling in stations for me.

e. wayne Jan 07, 2015

41"w x 33"h x 5" deep.

william Jan 06, 2015

It is the same dimension as advertisement in box comes basically assembled for you little work to attach uhf

robert Jan 06, 2015

The dimensions are 41"W x 5-1/2"D x 33"H. It's a rather large antenna and would be difficult to get into a small opening. Most square attic openings that I've seen should be at least 33" diagonal, so you could still fit it up there that way pretty easily.

curt Jan 06, 2015

Ken, I don't remember. Mine is up at the eve of my home. Look up the specifications and it should tell you. You might also be able to disassemble it (if needed) to get it up there. BTW, it works great for me, being about 30-35 miles east of a major city. Best of Luck!

corey j Jan 06, 2015

We are about 65 miles from the local network stations and our antenna is mounted on a pole just above our roof line outside. We get excellent reception and would recommend this antenna to anyone. Very pleased with product.

linda a Sep 05, 2014

I bought two channel master 4228HD, i receive great signal but i also purchased the 7777 preamplifier and i recommend to purchase these products.

gintaras Sep 05, 2014

I have not installed this Channel Master because my wife started using Netflix and Hulu.n

james Sep 04, 2014

I think you should be good, based upon that distance and topography, as long as the channels you are looking for are in the UHF band. By way of comparison, I am about 35 mi away from Atlanta's transmitters. My house sort of sits in a hole and it is hilly between the transmitters and me. In the attic, my reception is okay; however, on the roof it does great for the Atlanta Channels along the UHF spectrum, and rarely pulls in high VHF signals. Hope this helps.

steve Sep 04, 2014

Thanks for getting back to me with this info

lloyd Sep 04, 2014

Thanks for the feedback.

lloyd Sep 04, 2014

Lloyd We bought this same antenna last year and installed it in our attic on a pole facing toward the direction of the towers that are about 40 miles away and it works great!! We get approx 35 channels for FREE! No more cable bills of $100 + every month! I would highly recommend it! I did however talk with a representative from Crutchfield to make sure that this was a good fit or the right antenna for our area in Oklahoma. Good Luck with your future antenna purchase Delana from Oklahoma

delana Sep 04, 2014

That's a similar application to mine, and my family have been happy with its performance. The good news is that you'll know right away once you try it, well within the limits of Crutchfield's return policy.

cary Sep 04, 2014

I mounted this in the attic by suspending it from the rafters on a pvc pipe using the provided pipe clamps/U-bolts. Towers are about 25-30 miles from my house with no major hills or mountains in the way. Looked up online the tower locations to know the approximate angle to aim the antenna. Works great with no amplifier. Crystal clear picture on 4 hd tvs around the house including a 62in in the basement.

aaron s Sep 04, 2014

Does this come with a wire to connect to the TV? If not, which one (or type of wire) should I buy? Does this come with a roof mount?

mary May 21, 2014

9 answers

It does not come with a post or roof mounting bracket. You need to buy 300 ohm tv antenna wire and the necessary connectors (coaxial cable connectors).

linda a May 22, 2014

Thomas, It comes with coaxial connection, So coaxial cable is required. It does not come with a roof mount. I like mine, does very well.

david May 22, 2014

There is no wire included to connect from the Ant. to the TV. It takes a standard coax cable. I think it is best not to include the cable because every application will be a different length and it is always best to not splice antenna cable. It does not come with a roof mount you will need to purchase that separately. It came with two U bolt type clamps that will clamp on to any pipe up to about 1 and 1/2 inch Dia. Good Luck

richard k May 21, 2014

Hi Thomas: Neither wire nor roof mount are supplied. You need to buy a regular TV coaxial cable to connect from the terminal of the antenna to the TV set (length of the cable depend of the distance between both, but a 25 feet cable can be enough). In addition, you need to buy an stand and tube to install the antenna on the roof (Radio Shack is an option) Regards, Juan S

juan May 21, 2014

Thomas, This does not come with cable or mount. You will need plain old coax for the connection to your TV. As far as the mount, the way I mounted mine was to use a piece of bent conduit and insert it into a flag holder, like what comes with a flag kit that you can buy from a local hardware store. If you don't have a bender for conduit (I didn't), just borrow one from the same aisle you buy the conduit from. I can't remember if it was 3/4" conduit or what it was, just make sure it fits snug into the flag holder. Then drill a hole through the flag holder and conduit and stick a pin through it so it can't spin around in the flag holder. Attach the flag holder to the side of the house, attach the conduit to the antenna with C-clamps, stick the conduit in the flag holder (this is the tricky part, since the antenna is somewhat cumbersome and you're most likely on a ladder trying to stick this thing in), put the pin in, and you're good to go. I would buy a signal amplifier ($15-$25 ) if you're run is longer than 30-40 feet. If you would like some pictures of my setup, I would be happy to share them. All of the material I used cost me under $50 and I've been cable free for more than a year now :) If I could make one more suggestion concerning recorded TV, if you are like me and have grown attached to your DVR, I would look into a TiVo. It's the best of both worlds! I can pause and rewind live TV and record shows that I want to watch later just like the cable companie's over priced boxes. Just make sure you get one that records over the air. Good luck! David

david May 21, 2014

The antenna comes with a transformer, but does not include any wiring. You would want to get some RG6 coax and connectors to run to the television from the transformer. The transformer has flying leads which attach to the antenna.

jeffrey May 21, 2014

No it does not, but it uses a standard coax cable

publio May 21, 2014

it works well however it does not include a coaxial cable or a roof mount, it is designed to clamp on to a pipe or tubing such as is common for antenna mast. I used my existing coax that I purchased from a local store for the previous antenna.

wally May 21, 2014

It comes with a female coaxial connector, that mounts at the center of the antenna. (See black box in photo) Mine came with two mounting brackets for a vertical mount on a flat surface, not a roof mount. As far as type of cable, consult your Crutchfield rep, and they will guide you. Hope this helps...

My power and cable went out during the most recent ice storms for 4 days, but the antenna had no problems with weather and gave a clear picture while my house was running off gen power. I do not have mine on a rotator.

tyler Mar 18, 2014

I have not used it. Sorry.

ray Mar 15, 2014

I purchased this antenna and the 7777 preamp ignorantly, not realizing that I needed a directional antenna for my location. I returned this antenna because it was not Tue correct one I needed

michael Mar 15, 2014

I think the antenna is great. I receive HD stations in higher quality than with the cable service I had previously. My antenna is mounted in the attic in a fixed position pointed in the direction as specified by website that assists with direction pointing based on zip code. Search antennaweb dot org. I have no rotator installed. I recommend this antenna.

gregory Mar 14, 2014

Richard We've had our share of wind, rain, ice and snow since I put up the 4228HD and it has performed flawlessly. I don't have a rotator so I can't comment on that. The signals I'm picking up are from towers that are about 75 miles away and I get a signal strength in the high 70's . The picture quality I get is great and that is after it goes through 100 feet of coax. The only thing that was a surprise to me is how the antenna 'whistles' in a strong wind. It's not a problem for us as the antenna is mounted far enough away from our deck and porch that we don't hear it.

regan Mar 14, 2014

Got this question from Crutchfield. Unfortunately I can't give you an answer because I have not yet installed the unit. Need to add an electric outlet need the unit and as on now have not installed the outlet. Sorry.

william j Mar 14, 2014

I don't know. I returned mine because it was damaged during shipping and they were out of stock to send me a replacement..

homan Mar 14, 2014

It holds up to rain and wind without a problem. I live in GA, so snow is not a regular occurrence; however, we had a stint last January (2014) with snow and ice and there were no problems whatsoever. It has been rock solid. I have it mounted on a J-Mount, which is fastened to the roof decking via four self-drilling screws. Generous amounts of roofing sealant on all four screws and around the edges of the mount face have ensured no leakage. It has been rock solid so far. As for a rotator, I do not use one since all of the channels I seek are within 10 degrees or so of each other in the direction of Atlanta.

steve Mar 14, 2014

I mounted this in a fixed position, since that picks up all the stations in my area. A rotator was not needed. As far as ice and snow, there was no issue for me this past winter in spite of the bad weather we had. By the design of the antenna it is basically transparent to wind, so no problems there. I have not encountered any weather related issues so far. My wife and I have been delighted with the overall performance of this product.

jeffrey Mar 14, 2014

Richard, I live about 30 miles east of Nashville. We had a cold winter however, very little snow or ice. I did not have any problems. I have the antenna split to three tv's and it has not given me a bit of trouble. Hope this helps.

corey j Mar 14, 2014

Did you purchase the 7777 pre amp or the 3414 with the the antenna? How is it working overall for you, what area of the country are you in? Thanks

howard Mar 13, 2014

9 answers

Howard, I did not purchase a pre amp or other the 3414 with the antenna. I live in the Raleigh, NC area and the antenna works well under normal weather conditions. It's a little sporadic during storms.

chad Mar 16, 2014

I'm in western New York State. I bought this to replace a damaged Radio Shack antennae. It is unaffected by wind, snow, or rain. I was disappointed to find it was unable to draw in Canadian signals (100 miles away) as my old antennae did. To be fair, however, THAT was with the old analog signal . I did purchase a signal amplifier but it made no difference and Crutchfield was good enough to take it back.

steven Mar 15, 2014

I purchased this antenna ignorantly, not realizing that I needed a directional antenna for my location and subsequently returned it.

michael Mar 15, 2014

didnt need anything, live near Pittsburgh.

james Mar 15, 2014

We are in the Midwest and only purchased the antenna. The signals we pick up are from towers that are about 75 miles away and then they go through 100 feet of coax before they get to the TV. During the initial setup it picked up over 50 channels of varying quality but that has since been trimmed down to about 20. The channels we watch come in with signal strengths in the high 70's. We are very happy with the performance of 4228HD.

regan Mar 14, 2014

I bought the antenna only. I mounted it in my attic and patched into my existing coax cable line in the house. We get great signal throughout our two story house, even in the basement. We have 5 hdtvs using the same signal. We are about 20 miles from most of the towers in the Kansas City area. I would definitely recommend.

aaron s Mar 14, 2014

I live about 35 miles east of Atlanta, GA. I do not use the preamp because UHF signal strengths in my area do not require it and I am not trying to get channels beyond Atlanta. Saturday and Sunday football are awesome with it and my HDTV. The antenna has worked well for UHF. It is mounted on my roof, which makes a big difference over being in the attic. I get all the major stations on the UHF and, usually, some of the lesser ones which I rarely, if ever, watch. If you want VHF, then you may want to try a preamp or join it with a separate VHF antenna, which is what I did for a while; however, I disconnected the VHF because the two channels I would get were not worth the hassle.

steve Mar 14, 2014

We live in suburban Richmond, VA. 3 of the 4 broadcast towers in this market are in a nearly straight line from us, approximately 20 to 35 miles away. I do not need a rotator to pick up the 4th tower even though the reception angle is not optimal. The antenna picks it up anyway. And we do not need to use a preamp or amplifier of any sort to get clean, clear reception. We have been very happy with the performance of this product.

jeffrey Mar 14, 2014

I am using the antenna as a stand alone without amplification. I am about 30 miles away from my source. USA
