Style: 70 Mile
This antenna is great. I got the long range 70 mile antenna and it replaced a antennasdirect 4v antenna that I was getting nearly 57 channels with. IT was $149 at best buy and did ok for signal however gave me frequent drop outs. The VHF CBS channel that was 46 miles away wouldn't show up at all, but that was expected. I live in an area of northern illinois where signal comes from many places, namely Chicago and Rockford. All of Chicago according to TVfool.com was a "weak" purple signal area at around 46 miles away. Not only does this antenna work better, it was almost a third of the price, gives me 81 channels (not all are perfect but most are repetitive channels coming from different broadcasting areas) and i'm actually getting that CBS VHF signal, 46 miles away! The only thing I would like to see better, is some kind of stronger mast bracket. It works well, but we got hit with some 60mph gusts a week ago and it ended up turning the antenna from where it was set. I got back up there and it was already very tight. This could be the mast's problem just as much as the antenna so it's not fair to put the blame entirely on the bracket.

Exceeded expectations !
Style: 70 Mile
Regarding the HDB91X - All I can say is Wow! An excellent design that has by far exceeded my expectations for its performance. Heres some advice for those that are in a fair but not exactly in the best place for reception as I am stuck with: For my location, this antenna picks up ALL stations when aimed at los (line of sight) and 1edge stations. See tvfool dot com for whats available in your area. It also picks up 2/3 of 2edge stations as well. Unbelievable. My old school roof mounted made for analog tv uhf antenna did not even get a detectable signal from stations that this antenna pulls in strong. Next, I realized that antenna rotors are a real pain with digital tv as you need signals from all stations at the same time when you do a tv channel scan. But stations could be located in opposite directions, so rotating and having to rescan every time you rotate is just a pain. Even more of a pain if you have more than 1 tv in the house... The solution is to aim this at the far away stations and aim another antenna the other direction. You can use a 2-way splitter on the roof to combine signals from both antennas before going into a roof mounted pre-amp, but for very weak stations, the splitter acting as a combiner could weaken signals before entering the preamp. If you are in a VERY marginal area, run two antennas, each with their own pre amp and feed line, and then on the ground, combine the signals coming out of the pre-amps that power the amps on the roof. Dont put anything between the roof mounted pre-amp and the pre-amp power supply injector. There has to be an unbroken path between the antenna pre-amp power injector and the antenna mounted pre-amp to power the amp on the antenna. Combining the signals after they are amplified is the best way to preserve very marginal reception. One amp should be fine for most folks though. After combining the signals or after your single pre-amp, feed that signal into a 4 or 8-port distribution amp (usually a low gain like 4-5 db) to prevent your signal from being loaded down if/when connecting more than two tv's on the line. Now when you do a channel scan, your tv will see all channels at the same time - and that is so much easier than having to rotate and rescan all the time! Another point - the HDB91X is designed to sit on the top of the mast, so only one of those can be on a mast. If you are like me and are between two cities and have only one mast to work with, you will still need another high gain. The solution was to put a HDB8X-NI below it, aimed another direction. I got slightly better results aiming the HDB91X at the more distant city. Use RG-6 Quad shield or better - do not use RG-59 as it has a lot of loss. This is a UHF antenna and it is not designed for VHF channels 2-13. It may pick up the higher VHF channels 12-13, but not well. This is because vhf has much larger wavelength which this is not designed for. It is designed for uhf only. Get and combine a vhf high antenna if you need to pick up channels 6-13 too. The best way to aim is to use tvfool and aim in the general direction. Then take a small tv on the roof that has a signal strength indicator and dial in the RF channel. Loosen the mast just enough that you can twist it to get it in the perfect spot. The photo is the new hdb91x up there and my old school UHF antenna (which is total crap compared to the 91x), before I replaced the old school with the HDB8X-NI. The third antenna is for a local VHF-hi (channel 7-13) channel. Stellar labs, VHF-HI TV Antenna - also an excellent antenna. Last, the HDB91X antenna is so sensitive that I have occasionally scanned and by lucky coincidence, have received stations over 150 miles away with perfect clarity - those are rare atmospheric flukes and they may only last a few minutes before fading away. You may not see that phenomenon on that channel again. Point is, I've seen that before with analog years ago, but never with digital until I put the 91x up. That's two weekends of my time messing around on the roof, and what I learned. By the way, the whole reason for this is that Comcast raised my rates to a point where I dropped their TV (kept the Internet though) saving me $70/month. Wanted to maintain equivalent service with a variety of channels as cable did. Getting almost 40 channels of high def to all the TV's in the house now too! Picked up a viewtv at-263 for my dvr - can record hdtv to a flash drive that you can play on any pc with vlc player - nice! $39 for the dvr! Be sure to ground the antenna to a ground rod and make sure that you have a surge protector between the pre- amp and the distribution amp. P.S. We used a PCT-MA2-8P 8-port distribution amp when we had cable tv to clear up some missing cable channels. We only ever used 3 ports of it when on cable - meant to get the 4-port version - but since dropping cable tv, this 8-port amp also works perfectly with over the air broadcast tv too. Hope that helps.

Low cost, High gain, but Frail
Style: 70 Mile
Review of Xtreme Signal HDB91X VHF/UHF Yagi Outdoor TV Antenna. I’m a retired broadcast TV engineer and live 60 miles from Chicago. Recently moved and needed a good antenna for my deep fringe location. I mounted it in my ranch home attic and was able to get good reception on all Chicago stations listed down to 40 dbuV/m using a good (19dB) amplifier. This antenna works very well for UHF but it has some issues. First it may be able to pick up some VHF stations but only at a close range. VHF however may not be an issue as most stations are now in the UHF band. Because of virtual channel labeling the only way to know what channel your favorite stations actually transmit on is by looking it up. A very good tool for selecting an antenna is from the FCC search FCC dtvmaps At this site you can pinpoint your exact location and it will tell you the expected reception quality. Also if the repack changes will affect its channel or even location. What they term moderate reception (yellow) will very likely work with a 4 bay bow-tie antenna even mounted in an attic. You will need an amplifier of some kind depending on length of cable and number of TVs. The HDB91X is also very frail, I don’t think it would last long outside. Winegard, Channel Master, and RCA make tougher antennas if you have to mount outdoors. Again the big wide elements for VHF may not be needed, check UHF only. The HDB91X is also very directional. Gets its best signal in a 20 deg. Arc. If you have stations in different directions the bow-tie antennas have a broader arc of reception. Be careful putting it together it is possible to mount parts upside down. Look at video and freeze closeups if you need to see better.
