ADTech, Thanks for your input. I appreciate it. The Longley-Rice coverage map for the future home of KYCW-LD doesn't give me much hope, but it will be broadcasting from a 2000' tower, so I've got to try. I'm getting 32 channels/subs reliably now. I acquired a 50' Rohn 25G, so I'm going to gain 15' in height soon, which should help.

Should I get another 7777 and run another coax in the house and combine them inside? Eliminate the UVSJs and go with something like an RCA TVPRAMP1Z? Can two preamps be ran off of one power supply? Something else?

Also, I think I know the answer, but is there a method of combining the 4 antennas that doesn't introduce the loss of a splitter/combiner? Multiple tuners are not an option.

Thanks!
