Follow-up: I got every thing set up yesterday and have great signal to 4 recievers: Haier 32" HDTV, Zenith converter box feeding a Samsung DVD recorder/VCR combo, Channel Master DVR (which won't decode channel 12 anymore) and a 7" Haier TV by the bed. A couple of the more sensitive tuners are even able to decode KPLC (RF7) from 75.5 miles away, and the antennas are only up about 15-16 feet. So apparently, the splitter I first tried to use was a POS, or the jumper cable I was using had gone bad (who woulda thunk, huh?).
Anyway, thanks again for all the feedback and help. I am good to go. I am gonna try to take a week of vacation next week and if I can, I am gonna try to take a day and get that FM antenna up and running, and if that happens, I can reset the FM trap on the CM 7777 back to "in" on the TV antennas.
