I am able to get very strong signals from channels 29 and 43 which are located over 100 miles away but the transmitters are on a heading of 357 degrees which puts the towers in the plains and not the mountains. These channels also show no signal in my area on Rabbit Ears. I can pick up with good signals ch 13 and ch 15 which sometimes degrade when it's very hot; that transmit from the mountains west of Denver about 70 miles away. Ch 13 is at a heading of 327 degrees and ch 15 is at 341 degrees from Lookout Mountain near Golden; also the location of the channels I want to receive which are network stations that have very good news programs. Of the signals I can get are 4 in Spanish, 3 PBS that I also get locally on a translator here, ION, Qubo, shopping, GetTV and Bounce. I am trying to get some of the other subchannels that provide programming that will allow me to "cut the cable."
OK, that's a lot of information. Looking at the signal strength meter on the TV for the channels I want to get I see a bouncing signal strength ranging from 0 to 40 very quickly and no amount of rotor movement can make the signal solid. I am getting two stations with signal strengths in the 30s and 40s but they are solid signals. That stations that are 100 miles away have signal strengths in the 80s. Indeed, ch 15 came in after I put the preamp on and without it the signal strength never got above 35. The radioshack amp has a switchable box next to the TV; it provides DC to mast preamp mounted at the combined output of the UVSJ. Whenever I turn it on and increase the amp gain signals got to zero so I keep it off and the only amplification is the preamp at the antennas.
I think I need help in detuning some of the local signals. I also recognize there may be multipath issues. I would appreciate any advice to help improve the signals and I am very patient in trying a number of options. If I need to put the V ant over the U I will try. I have tried both antennas separately without the UVSJ and have not had any improvement. As a matter of fact the UVSJ doesn't seem to have any signal loss. I have moved the antennas from one part of the roof to another and there are no close in obstructions between me and the horizon but there may be an 8 to 9 thousand foot mountain in the way. I am picking up ch13 with the antennas aimed at the mountains north of me.
Thank you for your patience in reading this tome. I would rather give more info than less. I know must be there a solution to my problem.
