I purchased a Talking House 5.0 transmitter along with its companion ATU a couple months ago. I'm using a 102" steel antenna whip and 100 feet of RCA RG-6 coaxial cable, but I can't seem to get a reading on the ATU.
I had it downstairs in the basement with the mast resting on a copper water pipe and got a slight reading, but not when it's mounted to my roof, about 15 feet above ground. According to the instructions, Talking House supplied 100 feet of coax cable with the setup, and for the excess length, to coil it up, and not cut it.
I tried to ground it to the lightning rod outside my house and to its mounting hardware, but still no reading and no signal. What is it that I'm doing wrong here?
