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.

When my rotor recently gave up the ghost, I decided to get (the amazing!!!) SmartKom preamp and combiner. I needed another antenna to pair with my existing Televes DAT BOSS LR Mix and decided to snag the 4228HD as an open box. My plan with the 4228HD was to point it at my best market (Madison) and use the LR Mix to handle my desired (and toughest) market, Chicago. I hoped that with the SmartKom and two antennas, I'd get Madison and Chicago as a streaming service covers my Milwaukee channels. Maybe I'd get lucky and it would pull in Rockford as well as it's within 180 degrees when pointed at Madison. My expectations were BLOWN AWAY. On its own, this antenna is decent. I hooked it up before the SmartKom arrived and it's still very directional with some wider coverage. I was able to get strong Rockford stations pointed at Madison. With the SmartKom? It's nothing short of amazing. This pair allows me to pick up THREE markets while pointed at Madison as I can get Milwaukee and Rockford both off of just this antenna. I figured the 180 coverage claim was nonsense, but with the SmartKom, it is totally legit. The only advice I would give is that this antenna is HUGE so make sure your pole is long enough to deal with it. Assembly is super easy, and it's not heavy at all, but it's big. I can't recommend the SmartKom enough to pair with it; even if I were just using a single antenna, I would get it. It does a fantastic job of turning a decent antenna into an amazing one with tons of control. If you're in a rotor situation like I am it's a total no-brainer.

I had been having a lot of problems with my fringe area standard antenna since the inception of digital TV. Through research I found out that TV stations are no longe broadcasting on the same channel as the channel number. In Chicago, all but two stations are now broadcasting on the UHF band. Channel 2 is now broadcasting on channel 12 and channel 7 is still broadcasting on channel 7, thus still on the VHF band. If all the stations here had moved to the UHF band, one would only need a roof UHF antenna which are not as bulky as VHF/UHF antennas. The long elements of VHF or combination VHF/UHF antenna are only used by VHF actual brodcast channels. So if you live in an area where all the TV stations have moved to the UHF band, you no longer need that bulky VHF/UHF antenna on your roof. Just get the best UHF antenna that you can find. I live 42 miles from the transmitters in Chicago, so I live in a fringe area. Now since I needed an antenna that covered the UHF spectrum as well as VHF channels 7 and 12, which utilizd a design without the long VHF elements and had strong UHF elements, I had a problem until I discovered this ChannelMaster antenna. It covers VHF channels 7-13 and UHF 14-69. The description of the antenna fit my needs perfectly. It looks like a pretty descent UHF antenna but has VHF capabilities. I ordered the antenna and switched out my old antenna with the new one on the roof. Voila! Pefect reception on all channels and no channel drop out, even on the VHF channels. I've read that even though this antenna isn't rated for channels 2 through 6, it did work pretty well on those channels. The description says that the antenna will work pretty good in an attic, although I have my doubts in a fringe broadcast area. Now if you think that you need a new antenna, just don't go out and buy any antenna. Find out what the actually broadcast channel is for all your stations. There's a setting on pratically every TV that will tell you the actual broadcast channel. There are also web sites that will tell you the actual broadcast channel numbers in your area. If none of your actual broadcast channels are lower than actual broadcast channel 7, then this is the perfect antenna for you. Even if none of yor channels are still broadcasting on VHF, this is still a great antenna for UHF. It does look a little weird compared to TV antennas that you are used to seeing, but it is remarkably smaller. I am ecstatically happy with this antenna. I personally think that it has a greater range than what is listed in the specs.
