Ed, the distance from the Miami antenna farm to Key Largo is approximately 60 miles. I live by FIU and my distance to the Lantana site is about 60 miles also, and the WFLX-DT signal comes in at 95% on my Sony HD100, using an 8 Bay Bow-tie antenna. You might run into some problem with WPLG, as they don't run a lot of power, and they are on VHF Ch.9. I use an Antennacraft 10 element Ch. 7-13 Yagi, at about 20 feet, and their signal is about 86%. I am not sure whether the antenna you want covers those channels. Channel 8 (Fox) is from 180 Mhz-186 MHz, and channel 9 (ABC) is from 186-192 MHz. One thing I recommend is a rotor, as there are funny multi-path signals that can kill the DTV reception. I have a problem with the new Ch.33 (on DT 32). If the closest analog station has a lot of multipath (ghosting), so will the DT. I have no problems with 17 and 23 analog, so the DT stations on 18, 19, 22, and 24 come in (98%, but I do get a lot of ghosting on 33 and 39, and the Ch.32 DT is unusable, constantly breaks up. If I rotate a little, I can get it fine. Channel Master sell a very nice rotor that has a remote control, and you can preset channel bearings on it, and it goes perfectly to the stations. I just bought a Deep Fringe Yagi for UHF from Antennacraft, and I am waiting for a chance to put it up. The target is the NBC station in Ft. Myers. With my antenna now, I get it from the side, as I am not aimed at it, but once I aim at it, I think I will pull in a good signal 90% of the time. Love testing this stuff.
