We live about 70 miles from the broadcast towers in Dallas, and were having problems with pixelation, drop outs, and some channels that broadcast from the same location not showing up at all. I installed this thing and those problems disappeared. It's about as large as a radar antenna- so don't be dismayed when it arrives. Setup is easy- I installed it in my attic in less than 20 minutes. It's almost like having satellite. Now we get all the Jesus channels- home shopping channels- mexican channels- and the mexican Jesus channels just fine- plus the three or four we actually watch.

Over time I am trying to move my home and family to the “cord cutter” nation and have developed an overall (possibly too ambitious) plan to do so. One of the large parts of my plan is to utilize Over The Air (OTA) TV channels which is why I purchased the Channel Master CM-4221 HD antenna. As background, I have been marginally involved in video and video distribution for a long time. Channel Master is one of the brands that has always served me well. To be frank, this antenna was the only one I have tried for my home because it works so well for me. As always, Your Mileage May Vary. Luckily I live between 9 and 35 miles of the transmitters for 16 stations which, combined, broadcast about 40 distinct channels. Being this close means that I receive fairly strong signals at my house. Additionally, all but one of the transmitters lies very close to each other to my southeast. Specifically, they are within about a 32 degree beam width for those familiar with antenna parameters. How do I know this? I used a wonderful Internet resource called Antenna Web (https://www.antennaweb.org/). Just plug in your address and it will tell you where nearby transmitters are and will guide you as to what type of antenna you need to receive them. Between the proximity of the transmitters and the fact that they are mostly bunched together I have a situation where I can use a relatively small, mostly directional antenna like the 4221. This was great news because, due to homeowner’s association rules, I had to install the antenna in my attic. The antenna comes about 95% assembled and all you have to do is unfold a couple of antenna elements (the bow tie looking wires in the picture), attach the balun that connects your coax / signal wire to the antenna (that black box in the picture), and the clamp that holds the antenna to whatever you use to hold the antenna upright. All told it took about 10 minutes to perform all of these minor mechanical tasks. After installing it in my attic, which took a lot longer than 10 minutes, I connected the coax in my house to a digital receiver to see how it worked. In a word, it was fantastic. Digital TV is incredibly forgiving when it comes to being able to drag in TV signals but because I plunked my antenna in an attic behind a roof and lots of rafters I was a bit worried. I needn’t have been as this antenna works like a champ. I had to make some minor adjustments to properly aim the antenna at the transmitters, but that was my fault. If I had been smart I would have carried a compass up to the attic with me when I installed it rather than taking the classic male “Oh, I’m sure I know where I am” approach. A couple of things to note: 1) I don’t know if it is necessary, but in my opinion you should plan on supporting the coax you will connect to the antenna with something more than just the balun. I mean it looks good and strong, but to be safe I used a zip tie around the coax and the antenna mount to take some weight off the balun. 2) Antennas are sometimes marketed as black magic and companies will make all manner of claims about range and gain. Without much searching you’ll find companies claiming that a tiny “rabbit ear” antenna perched on top of a bookcase in your living room has 60 mile range and 20 db of gain. When comparing antennas look for external reviews and be VERY skeptical of small cheap antennas that claim to have incredible performance. This antenna does everything it promises and is an excellent value for its price.

Still works great after a half dozen years hanging 30 feet off the ground.

Keep in mind that I live on the outskirts of Austin, TX, within a 25 mile radius of all the transmission towers. The towers are on the sole high hill in the area and the land here is flat as a pancake. If you're in the mountains, live a long way from the transmitters, or in a city surrounded by tall buildings, your results will not be the same. (1). Price is not a value. All the reviews said "Get a quality antenna like a Craftsman for best results" so that's the brand I purchased. When it arrived it was about $10 worth of thin aluminum tubes. Come on, for $85? It was a small box within a much larger box, like one of those goofy Christmas presents. I doubt it cost the company $15 to make even with the labor. When I dropped it (and you will drop it if you mount it on a 10 foot 1x2 and climb up a 24 foot ladder and a good gust of wind comes along before you can get it fastened), the outer tubes, which are held on by pop rivets and cannot be tightened, came loose. I had to literally tie them back to the mast with twist ties!! So minus one star for the cheap quality and the high price. Value for price aside, once installed, it worked like a champ. I don't know how long it will last as we often have wind gusts over 35 mpg. I did not extend it on up above the top of the chimney because it was way too high (I'm 75 years old, and I was already afraid I was going to fall off that shaky aluminum ladder)! But it didn't seem to matter as all the channels come in crystal clear. Now I can get rid of basic cable (which just went up to $245/month with Internet). I purchased fiber optic Internet - 500 Mbps, fiber optic, get my local channels and much more over this antenna, and can purchase a streaming service for remaining TV/Sports. Streaming services don't charge you box fees, consumer fees, FCC fees, Local Programming Fees, taxes and surcharges like the cable companies. And streaming services start around $65. or less depending on what you want. I'm glad I was able to cut my cable/internet in half and don't have to worry about it going up as soon as the "promotional period" is over any more. FREE AT LAST!
