Well, weather broke. Was able to get it hoisted up and secured. Did not play around with the variable amp much, but it all works and is solid. Time will tell as always. SNR ratios on my old 194 pound Sony CRT indicates 28 - 32 SNR on these two channels. Can check for more detail on my Aero-M once it is not recording. Does what I needed.
Filter in front of amp, I've got it going through my new gear, but then also scabbed into my existing setup with another UVSJ hooked to my existing UHF. More upgrades in the weeks ahead... Thanks all, very helpful as always guys pointing me in the right direction. I really appreciate what you do.
