About the Channel Master 4221HD

Channel Master's model 4221HD antenna can receive digital and analog over-the-air TV signals in the UHF band only (most digital TV signals are in the UHF band). The 4221HD is optimized for distant "near-fringe" reception of HDTV. Its space-efficient design is suitable for roof and attic installations. For years, I've been getting great results with a 4221HD installed in my attic.

Product Research

Features

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
Can this antenna be mounted on the wall indoors? Can this antenna receive stations (UHF/VHF) within a 40-50 range of zipcode 12180?

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.

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.

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.

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.

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.

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.
