(I have 100 feet of tower to erect to whatever height is required & a HyGain Ham IV controller and rotor to install on the tower.)
I live in a hollow in St. Albans, WV 25177, GPS N38.20.434 / W81.52.807. The view to the north & south are obstructed by mountains. The feet above MSL 707.
If you believe these antennas are adequate, what pre-amp would you suggest to combine these antennas at the mast and any other suggestions you might have. My interest is in a digital signal only.
Thank you in advance,
Charlie

The PA-16 does not indicate what its overload characteristic is. It may be overloaded, it may not be. The one preamp designed for high signal levels is the Winegard HDP-269, but I feel that your analog channels 3, 8, and 11 would tend to overload the HDP-269. I used a VHF/UHF splitter before my HDP-269 to eliminate the VHF signals, but it was no better than a Winegard AP-4700.
If you need even more overload resistance you would have to filter the lower & upper UHF channels, amplify them seperately, and recombine them in another filter. The only place that I've seen such filters in Triax in the UK.
