beautiful picture quality

Exactly what I needed to pull in all local stations. Great picture quality.

Pros: Easy to setup and install

Cons: None

Much improved reception

Eric from Va Beach, VA on 7/26/2017

Crutchfield Customer Review (What's this?)

The antenna came on time in great condition. It was easy for a non- tech person like me to set up. I did an attic installation - used tv fool to orient the antenna and mounted it on a vertical pole hanging from a rafter. I was using a set top antenna and getting fair reception except during bad weather. We have a LOT of big trees. Now I get one or two more distant stations but the best part is all my local channels stay crystal clear. No more adjusting the antenna as we change channels!! Goodbye cable!

Pros: Great reception Easy install Good price point

Cons: None yet

Works Great!

I'm pulling in stations from 30 miles away through tree foliage with antennae inside the house. Can't wait to see how it does once mounted outside. Highly recommend this product.

Crutchfield Customer Review (What's this?)

Pretty good antenna. The channels will fade in and out when the wind blows. It is mounted on a pole outside about 25 feet in the air. I will probably put a booster on it.




Rob from North Carolina on 10/28/2015

Crutchfield Customer Review (What's this?)

Good compact outdoor antenna. Easy assemble and installation on a chimney pole. Easy to aim, it is more directional than omnidirectional as advertised

Pros: Inexpensive, small and light weight especially good when standing on a high sloped roof. NO Cable bill nor cable bundles of worthless channels. The channels I receive are clear and excellent.

Cons: Does not receive stations beyond thirty-eight miles as noted on "tv-fool" mapping. I have receiver twelve channels.

Gman from Massachusetts on 10/18/2015

Crutchfield Customer Review (What's this?)

Purchased this antenna after having a terrible experience with DirecTV as well as sick and tired of paying for cable TV. Antenna arrived in 2 days. I simply took it out the box and hung it from a rafter in the attic, tied it into the existing cable splitter and that was it. I now have great HD reception and a whole bunch of free channels on 3 TV's. I think in the end if you can do without local sports channels and ESPN you'll survive and save about 100.00 per month. Between Netflix and the Channel Master DVR that was also purchased you'll save quite a bit of money in the long run.

Pros: Works well in the attic, did not need exterior mounting.

Cons: None

Perfect for local channels

PeteOwl from Wisconsin on 8/28/2015

Crutchfield Customer Review (What's this?)

We cut the cable tv wire and got a wall mounted antenna. Since we are only 7 miles from downtown we figured no problem getting signals. Wrong! I upgraded to the amplified version, but still static (pixels). My neighbor has one in his attic, but it still breaks up. I chatted with an advisor who suggested this one and mounting on a pole. We are slightly down and not really line of sight from the stations. After 2.5 hours of installing it was amazing!! Picture is perfect - all stations -- no pixel effect at all. Given it cost $100 total to install, but getting rid of cable is saving me $90 a month, well worth it. My neighbor is getting a outside pole and asked for my help :}

Pros: Very lightweight -- I installed in medium winds. Picture is perfect!!


Good Antenna

Steve from Michigan on 6/25/2015

I live 10-15 miles from Detroit's transmitters and tried a couple antennas made for digital reception. One was a rectangular plate and the other had two adjustable antennas with an amplifier. They both had to be in just the right position to be semi-reliable. They often failed to pull in the channel I wanted to watch. They were incredibly frustrating to use. I ordered this antenna and couldn't be happier. I get more channels than I did before and every channel I wanted from Detroit comes in perfectly clear. I've had it for a few weeks mounted in my attic and it's been a pleasure so far to use! The only incident I had was that UPS delivered this thing next door. I thought it had gotten stolen :) By the way, you need to purchase mounting hardware to use this. It comes ready to mount to a pole.

Pros: Reliable, well-priced


Works just fine

MarcoM from Florida on 6/22/2015

Crutchfield Customer Review (What's this?)

Our local channel antennas are about 20 miles from my home. I was using an indoor RCA amplified plate antenna sitting in my front window before. It allowed drop outs frequently, especially during storms. I installed this Channel Master in my screened lanai facing directly toward the area of the local channel antennas by hanging it from a vinyl screen trim with two eye hooks. Now I have no drop outs and all channels remain clear all the time. The antenna boasts that it is a 65 mile antenna but I can't personally attest to that because there are no antennas other than our local ones in that direction. Very nice design with plastic edge pieces to connect all the "reflector grid" crossbars which makes it look nice and is less likely for the user to get cut on it while installing.

Pros: Does what it's supposed to. Decent price. No powered signal booster required. Easy to set up. Raise the bow ties up as a group of 4 on a single bar and tighten two wing nuts. That's it. 300 ohm to 75 ohm coax transformer is in a waterproof box built onto the antenna so you don't need to buy one. Comes with clamp for antenna pole and rubber boot for the coax cable to be weatherproof if you are going to install it that way. I didn't.

Cons: The box was damaged when it got here. Three of the "reflector grid" bars were bent pretty badly but because they are soft aluminum I could press on them with my palms and get them back to almost straight again. I could use some large pliers and straighten them further but it's only the reflector grid and not the bow ties that do the receiving, so that's good enough. The box the antenna came in is very thick so somebody had to do something really terrible to it during shipping.

Channel Master 47 - Homebrew 33

Frank_M from Nash County, NC on 4/18/2015

Crutchfield Customer Review (What's this?)

Propped up my "homebrew" antenna on the bed and received 33 channels. This antenna received 47 without any amplification. Planning for an attic installation and will update my review afterwards. A great antenna for the price. No wonder Crutchfield is out of them. As soon as they are back in stock and you want to "cut the cable" this is a great solution. I live between two major broadcasting areas (Raleigh and Greenville) with about 120 degrees between the transmitters according to I`'ve pointed the antenna between the two and as stated before am receiving 47 channels. Most channels are beyond 40 miles with a handful beyond 50. When the weather is clear I`m receiving a set of PBS stations from 87.4 miles away! Maybe with an attic mount, an amplifier, and a rotor I can receive some of the southeastern Virginia stations! I don't get excited often but the performance of this antenna has motivated me to cut my cable. Lastly, it is receiving some high vhf channels as well.

Pros: Excellent reception, compact size, value priced, comes with mounting hardware and balun.

Cons: Potential exists for shipping damage as it is shipped in the manufacturer's box however mine arrived just fine.

Very nice antenna

captainfoo from Winter Springs, FL on 7/28/2014

Crutchfield Customer Review (What's this?)

Fit very nicely in the attic, and getting great reception.

Pros: Not too large for attic, great reception

Cons: It is shipped in the manufacturing packaging. I tried to purchase it somewhere else, where it was damaged in shipping. I returned it and ordered it through Crutchfield and had no problems. But feel lucky because it is not packaged very well.

Great Antenna / Una Gran Antena

Roberto H from Aguadilla, Puerto Rico on 6/24/2014

Crutchfield Customer Review (What's this?)

This antenna'm using in Isabela Puerto Rico. Our area is mountainous and TV towers are geographically remote. Best antenna for money. It works grate.

Pros: Best reception , easy installation , free hight definition network . Fast shipping .

Cons: None

Must have for small places

Jacob from Dublin, OH on 10/6/2013

Crutchfield Customer Review (What's this?)

Put this unit in my attic and the signal quality is great. Better than cable HD. Cable providers have to use massive amounts of compression to deliver 300+ channels so the quality suffers. Crutchfield always delivers quick. Picks up over 20 channels HD no problem with strong signal strength. Great size for the small access panel into my attic.

Pros: Easy install, great signal quality, and light weight.

Cons: None

Works Good

WesE from Somerset, VA on 6/7/2013

I am about 25 miles from the local transmitters in Charlottesville. My house sits fairly low and this antenna lets me get all the Charlottesville channels and some of the Richmond channels (60 miles away CH 6, 8, and 35) at the same time without rotating it. The Richmond channels are coming through the back of the antenna, so those signals are not as strong. But I am real happy that I it does not seem to be that sensitive to the direction. I looks like I should get more channels from Northern Virginia (80 miles away) once I get this antenna up above the roof and on the rotator and add a pre-amp. Right now I have a metal siding house and roof blocking those signals.

Pros: Low profile to mount along side of house. When viewed on edge the antenna disappears from the road. Much better signal and less finicky then the previous dept. store plastic amplified antenna. Solid strong signals for stations at 25 miles. Good enough signals for some channels at 60 miles away.

Cons: Does not work well for low or high VHF signals...but many of those are not around after the digital transition. You will need a mast and associated Hardware to mount the mast...but I had that already.

Great little antenna

Troy from Ohio on 12/4/2012

Crutchfield Customer Review (What's this?)

Installed the antenna and aimed between 2 major cities, picked up 43 channels. So long Direc tv. Before this antenna I had 8 channels

Pros: Comes put together, just install mounting hdw. Gets channels over 45 miles away

Cons: None


el from Remo VA on 2/11/2012

Crutchfield Customer Review (What's this?)

I used it with my camper on a recent trip to Fla. The camper's Delta amplified antenna only recieved one channel in the state park campground. I mounted the 4221HD antenna on a 12' pool cleaning pole and attached it to the side of the camper and it recieved over 25 channels. I saved the box and fold up the antenna for transport, it is a little big but I just throw the box on the bed during transport. Set up only takes about 5 minutes. The reason for the four star rating, when I first opened the box, the pop rivet holding one end element was not securing the element to the frame. I just drilled out and replaced the pop 3/16 pop rivet, no problem for me but for others you would have to return and replace the antenna.

Pros: Great reception. Could not have watched the Super Bowl without it while camping. Ordered one day and on my door step the next day before the trip with free shipping, that was great service. Free shipping with the the other online A site usually takes about two weeks for me to recieve an item.

Cons: Channel Master needs to inspect their antennas closer for defects prior to packing and shipping.

Free HD TV

W. McGuire from Lexington, Kentucky on 3/23/2011

Crutchfield Customer Review (What's this?)

The Channel Master 4221HD exceeded my expectations in its performance. I mounted the antenna in my attic, oriented toward the sweet spot for my area and picked up 16 chrystal clear channels with signal strengths well into the 90's on my signal strength meter. I can't imagine what I would pick up if it was mounted outside and at a higher elevation. I am sick and tired of paying high cable bills and having 3/4 's of the channels that are garbage. I am considering putting an 8 bay antenna outside and picking up more channels and perhaps some Cincinatti, Ohio stations and dumping cable all toghether. I would consider a splitter with the attic antenna but that probably would cut the output to the other tv's in my house in half. I would definitely recommend this simple but efficient antenna for free UHF reception.

Crutchfield Customer Review (What's this?)

Nice reception for a low budget antenna. I live in a mountainous area were reception is very poor and I can get a crisp reception for the channels available in my area. Installation is easy. I recommend this product and Cruthfield service is great and very important hablan español.

Channel Master 4221HD

Anonymous from Near Madison, Wisc. on 9/3/2009

Crutchfield Customer Review (What's this?)

Completely pleased with this antenna. At a distance of 35 miles, across rolling farmland, it picks up all the possible stations from Madison area. Antennaweb rated this distance and topography as "purple.' The antenna came completely assembled and was ready to put on a mast with minimal preparation.



Channel Master 4221HD

Elizabeth from Rehoboth, Delaware on 4/19/2009

Crutchfield Customer Review (What's this?)

Easy purchase with Crutchfield. Package arrived quickly and in perfect condition. Extremely easy setup. Hooked up to my tv in a couple of minutes and pulled in a station over 50 miles away, much to my great surprise since I had it temporarily propped up on top of a door inside the house with a 6' cable. It brought in questionable stations (from my double bow tie with rabbit ears) crystal clear and added about 50% more stations! Thrilled I made the purchase, will be getting another one for a friend.




Hands-on research

Product Research


Overview: The Channel Master 4221HD antenna is designed for UHF frequencies only (channels 14-69), both digital and analog. It can be mounted on a roof, on a wall, to a chimney, or in an attic.

Mounting Brackets: The mounting brackets and the U-bolt are used to mount the antenna to a mast. 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 12-1/4" 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 4221HD is 45 miles, 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 11.5 dB.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

Size gives me the ability to mount it in my attic. Reviews indicate it performs well in attic installation. Small set-top antenna I bought from Crutchfield is working well, but sometimes gets interference. From reviews and specs, this should be high enough to avoid interference from my brick house and neighbors' houses. I've been very happy "cutting cable" and using antenna for local channels, streaming for only the premium channels I want. [ Eric  Jul 12, 2017 ]

1 question already asked

I had this antenna mounted in my attic with a rotor and moved it outside due to some reception problems. This did not cure the problem but I think it is because of a very large tree between the antenna and the direction of most stations. As long as it is not windy it is OK. I use it with the amplifier. I have 100 ft of cable from the antenna to the amplifier and two TVs off of the amp. I did have an "omni directional" antenna with poor reception until I put a rotor on it. The Channel Master is an improvement. I am about 25 miles south of Buffalo NY and get all the UHF and VHF stations just fine. [ RICHARD P  Jan 17, 2015 ]
The antenna is quite sensitive to direction and location. If you want maximum performance it would be best to walk around with it connected to your TV and decide which location would be most suitable. This antenna would double your present signal strength and make marginal signals very acceptable. [ Nolan  Jan 15, 2015 ]
This is more of a UHF antenna than a VHF antenna, but mine did pick up the one VHF channel I cared about that was ~22 miles from me. As for your zipcode, I would check tvfool or antennaweb to see what it says. If you search for BigT on the dtvusaforum you will find the thread that led me to buy this antenna. It also includes some info on what to do if you need more help with VHF, though I did not have to worry about that as this antenna received everything I was looking for. [ Thomas  Jan 15, 2015 ]
Yes. You will need to go to the hardware store & get some mounts, I used 3 wall mounts and put it high near top of ceiling. You may do it differently as it will depend on the type of wall mounts and your situation. It works great when mounted indoors. [ Brian  Jan 15, 2015 ]
This antenna is to big to mount indoors on a wall of course you don't mention where in the house you want to put it. I have mine in the attic but I am not sure that it will work well up there. I'm still trying to figure out the best place to put it and it looks like outside on top of the house is the next place I'll try. To many things go into how well you pick up signals and it does pickup UHF/VHF, trees and buildings can effect signals and direction of the antenna in relationship to the stations can affect it. You might have to buy a rotor. I got this because I no longer want to give my money to Comcast and Hollywood in the form of outrageous fees. Good luck with your project as we both strike a blow against cable and satellite TV. [ larry  Jan 14, 2015 ]
I first hooked it up in my living room behind the couch. Worked fine for a couple of strong channels in the area. I moved it to the attic and reception was much improved but still struggling to find one direction to point the antenna without have to use a rotor. My goal was to fine one fixed location to use my Channel Master DVR to record programs on many channels at any one time. I ended up mounting it to the chimmey with a channel master amplifer. It was more involved than I orginally had planned, but the results have been very good. I received about 45 channels some as far away as 75 miles. In short you could mount it on the wall if that is your only option. Just know that every location is different and has obsticles to over come when mounting anntennas for great signal strength to your TV. With any antenna the higher up and less walls to go thru the better the signal. I hope this is helpful. [ Brian  Jan 14, 2015 ]
Works good have mounted in attic on brick chimney get stations 50 miles away [ Eric  Jan 14, 2015 ]
JD, I have mine mounted in my attic. I pick up stations 40 miles away but sometime I get an imperfect picture. Mounting on a wall is fine but you need to be able to have the antenna face the best towers. I would recommend the next level up for you and get a signal booster. This site has a wealth of information on where to find your towers and what type of antenna you need. Google antennaweb dot org for a great source of information. [ John  Jan 14, 2015 ]
