Our problem is we are in a valley. I am about 140’ above the valley
floor, but still the hills limit a lot of signals.

I am not sure why OTA sucks so bad here. OI am 30 miles from the
towers and it is flat ground. Looking down the line on Google I don't
even see any big buildings, just trees. I do have one big live oak
right here. The antenna is 25 feet off the ground and I am afraid to
stick a lightning rod up much higher.

I am running this, with an amp

How long is the cable coming down from the antenna, and what kind of cable? You get a lot of loss in that cable.



I kinda doubt that's his problem. The RF amp will more than make up for
any losses and actually there isn't much signal loss in the RF signal
cable anyway unless he has miles of it.

That's why I asked what kind of cable and how long. RG-6 can have upward of 6dB of loss per 100ft at upper UHF freqs, while the old RG-58 would be up around 16dB of loss. There's also loss at each connection point. As you point out, the signal is either on of off with digital TV, and UHF doesn't have long legs.

The cable is less than 50'
