I agree, Browns territory, ugh. I'm not allowed to move though, Weeze won't let me.
I think I figured it out. Some guys say you can just flip over a splitter and combine the two signals. They tend to overlap and cause problems, but sometimes it works.
I had to get
DC voltage/IR passing splitter/combiners because normal splitter/combiners block the dc voltage that I'm putting in on purpose to amplify my antenna signal.
In case the splitter/combiner option doesn't work, I got a couple simple
coax A/B switches.
I chose this pre-amp because it had a much higher gain for just a few more bucks.
