I have TiVo Premiere XL and this antenna in Venice, FL, about 42 miles from Tuckers Grade where most of the Ft. Myers antennas are.
With no amp, and the antenna inside the house, I get the six Ft. Myers channels I wanted (CBS, NBC, ABC, PBS, Fox, CW) without an amplifier (but remember, this part of FL is fairly flat). Signal strength is between 60-85, with S/Ns between 25 and 30dB. So far, I see very few if any dropouts, and PQ is better than Comcast.
Now when the Bucs are blacked out on Tampa TV, I can see them in HD anyways.
In case you're keeping score, these are all UHF channels.
Hey, if I had some place to go I certainly wouldn't be in 'Cleve-Land'.
