Product Description
Channel Master’s model 4221HD antenna can receive digital and analog over-the-air TV signals in the UHF band only. The 4221HD is optimized for distant “near-fringe” reception of HDTV. Its space-efficient design is suitable for roof and attic installations. The 4221HD receives digital and analog UHF TV signals (channels 14-69); range is 45 miles; 4-bay bowtie dipole design; 24-1/2″W x 5-1/2″D x 33″H; 12-1/2″ turning radius (if used with an antenna rotor)… More >>

I bought this on hype and the sad notion that I would mount this outside. I got it from Polstein’s (stay away) and was deterred from mounting it, once I got a load of all the “you can die” sticker warnings. I set it up indoors without a pre amp and got diddly except, KPIX. I know it probably rocks once its in an attic sweet spot or happily on the roof, but I don’t see it happening on a widescale in the future with people looking for hdtv from an ota. I found a rocking indoor antenna (RCA ANT706). I recommend finding the indoor antenna that rocks for you.

I read about this antenna on a couple sites, which recommended it as a great antenna for UHF frequencies, and not particularly directional. Unfortunately, not so for me- seems quite sensitive to direction for some channels, and doesn’t have the range (even with a power amp) I’d hoped for. also – be careful who sends it to you- the one I received was pretty beat up by the time it arrived; several element were bent quite a bit out of shape, since the cardboard box it was packed in wasn’t up to the task.

I bought this antenna a few weeks ago after a lot of research. I was looking to replace a set of rabbit ears to get a better signal to see if I could get my TV to PC converter to display Digital Signals. (That didn’t happen, but it wasn’t the antenna’s fault.)
During my research, I searched for 4221 and came up with a site that has the gain figures for a lot of commercially available TV antennas. The author used numerical methods to evaluate them. Only the 4228 had more gain, but it looked like it would be way too big to use in an apartment.

(I’m batching it right now, so no women are around to complain about it!
The only problem with the antenna was, as another reviewer stated, was the wing nuts were too small. I’ve tried 10-32, and they are too smal, and 1/4-20 are too big. (I’m not hauling the antenna to Home Depot to get the right size!) Luckily, the transformer leads were stripped, and as its inside, they are OK just wrapped around the studs.
Originally, I just used the new antenna, and got channels 24, 33, and 36, plus 10 and 12. The review site I mentioned said that this antenna would work on high VHF, and it does. Then, I decided to see if I could use my rabbit ears and the new antenna. The results were surprising.
My rabbit ear antenna has a cable input, and a switch to select between that input and the rabbit ears. I tried hooking the new antenna’s cable to the cable input on the rabbit ears, and got a couple of additional channels. I never got channel 8 on the rabbit ears, but with them hooked into the circuit, and with the switch set on cable, I get 3, 8, 10, 12, 24, 33, and 36. Channel 3 is a little better with the rabbit ears selected, but I can only get 8 and 12 with the cable selected. I have the rabbit ears behind the 4221, so I must be getting some sort of signal reinforcement from the rabbit ears.
The back of the antenna is a 1″ wire mesh. It is supposed to work as a reflector. I’ve been wondering what would happen if I covered the mesh with aluminum foil. Its a better conductor than steel, and is solid. The waves are too long to pass much energy through the mesh, but I’m sure there is some leakage.
Anyway, I’m glad I got this antenna.

I bought a channel master 4221. It comes form Polsteins Home & Beyond. They sent me a damaged antenna. I returned it and they sent me the exact same antenna back in the exact same box. It even had the note I wrote to them in the box. They just put it back in stock and then resent it to me. A very dishonest company. I still have yet to get my money back. DO NOT BUY anything form Home & Beyond.

My old big rooftop antenna was blown off during the storm. Instead of repairing the big and heavy thing, I tried this much smaller antenna. To save even more work, I managed to hang it at the top inside the garage and positioned it in the dominant signal direction, and then routed the signal to each room using existing cable and signal splitter. It worked perfectly and I got almost all the digital channels shown on [...], many labeled 60 miles away and a few of channels were not received well by the old rooftop antenna. Maybe my house’s location also contributes to the good result. Anyway, Channel Master 4221HD saves me all the trouble of setting up outside the house or in the attic while still getting quality signal.
