The Boston stations are about 15 degrees East of Due North and the Providence Stations are about 23 degrees east of due North. So I angled the antenna about 30 degrees to face the Boston stations. Providence Stations are about 30 miles away and Boston stations are about 61 miles. There is about 100 feet of Quad insulated RG-6 connected from the antenna to a distribution AMP which feeds two TVs, one only 25 feet from the Amp, the other another 100 feet. The 100 ft. run is old RG59.
I easily received 39 channels on both TVs. Every Channel with a Noise Margin over 10db comes in consistently without out any break-up nor artifacts. This included numerous Boston Stations. Several stations with a Noise Margin between 0 and 10 come in if I move the antenna to point directly at the heading of the tower. This is also improved if I install a Channel Master Titan Amplifier for which I was able to tune in about 60 stations, but then I had some break-up on the very close stations. With additional work I could probably fine tune the amplification as I have yet to measure the signal nor try different levels of amplification. I used a titan high gain amp but did not install the medium gain amp I have. They now have one with a switch I might try at some point.
The bottom line is that without any substantial effort, mounting indoors and not on the roof, I was able to receive all Providence stations, many Boston Stations and a few Connecticut stations that are 90 degrees from the direction of the antenna but close range (30-35 miles). There are houses in the path of reception and trees about 250 feet from the antenna. When considering this for an attic application, you will need to consider that for my application the signal is not blocked by insulation as it is fairly lucky that the garage peak faces the towers with only a 30 degree offset. Installation and mounting are very simple. You do want to be careful connecting the RG-6 to the antenna, do not over tighten - do not apply significant torque and when you unfold the antenna, unfold both sides at once to ensure you do not stress the phasing harness. This is shown in the instructions, it is not difficult and is really obvious and common sense. The antenna does not receive LOW VHF but there are no stations in my area that transmit LOW VHF. Remember that most stations with virtual channels from 2.1 to 6.1 are actually transmitting UHF or HI VHF at this point. There are several DTV sites that map this for you. Good Luck - I highly recommend this antenna.
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.
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.
Top reviews from other countries
Boy, did I ever get an antenna with good range! In theory, this antenna has an 80 mile range, and those theoretical numbers are usually under ideal, laboratory-like conditions. But with an antenna that's mounted about 30-40 feet high with several condos and office buildings in the area, I was still able to pick up a broadcaster that TVFool says is 90.1 miles away, with an NM of -23.3 dB, signal power of -114.2 dBm, and the signal path is tropospheric scatter. Basically, I shouldn't be getting this signal at all, but according to my TV, I'm getting a "Good" signal. I'm also getting a lot of strong signals from other US broadcasters in Buffalo (I'm in north Toronto).
This was not a cheap antenna, certainly more expensive than other options out there (and I seriously considered buying the cheaper antennas). But considering what my cable TV bill was before, I made all my OTA-related purchases with an eye towards how long it would take for me to break even after I save on cable TV costs, and the break even time for this antenna was very short. Considering that I'm getting 40 channels and subchannels without tweaking the direction of my antenna to hit that sweet spot, this antenna was well worth the cost. Channel Master is a trusted brand, and I can see why!
