well i guess i have much more success than you do with the silver sensor. WGFL has had a construction permit to have a higher tower powering up to 625 kw, but they are owned by pegasus, and they are in the middle of a chapter 11 bankruptcy, and all their stations they owned are on halt right now with thier construction untill they get through the proceeding. Another thing is that a station's tower does not change in power, what is really happening is a phenominon known as signal skipping. It is basically caused by temerapture inversions that end up warming up ions in the ionosphere causeing signals to bounce off the ions and reach a new target, even though that place may be very far away. On some rare nights, i can get WBBH, an NBC from fort myers (200+ miles from the towers) or get an ABC out of West Palm Beach.
Finally, remember that the tempory tower for WGFL is located near Alachua, WUFT is just a little south of it, but WOGX is located 25 miles south of town near wiliston. The silver sensor is an EXTEMELY DIRECTIONAL antenna.
