Hi Joel, thanks for the reply. I'm trying to get rid of the rotor altogether. The bulk of my stations are in the same spot almost due north, then there's a second group almost due east. I'd like to pick up both groups simultaneously without having to rotate anything. If I go the yagi route, it'll have to be two yagis and the gain of the two will have to be at least 3dB better than the U-75R to make up for the loss in combining. Optimally, I'd like the gain figure to be significantly more than 3dB better to get a stronger signal to carry me through the electrical storms and people flipping on and off lights in the house. I could get an antenna that's both VHF and UHF for my northerly channels, but looking at most of the specs it seems that standalone VHF and UHF antennas tend to have better gain. I only have a need for VHF high and that's only for two stations - one to the north and one to the southwest. I use the same cable line to feed my Sangean HDT-1 HD Radio so the FM broadcast band is a must. I have a 5 element FM yagi tied into the VHF side of the amp by itself right now, thinking of expanding that by adding a VHF high only yagi pointed southwest with the join-tenna for channel 12. Channel 8, the other station, is strong enough that it comes in anyway even if the FM yagi is less than optimal. I'm afraid without the join-tenna that combining the two will make channel 8 worse.
The big question in my mind is how to get this channel 35 in there. It would be a real bonus getting it tied in somehow but after some searching it almost seems like uncharted territory doing it without an A/B switch and doing it without a really expensive single channel notch filter. I'm thinking this cable box idea *may* work. Not with the newer ones which have actual tuners in them. Anything with a built in OSD definitely won't work. I'm talking 1980's vintage cable converter box. Will it work? Then next question would be if so, how well would it work since this signal is fairly weak. I'm sure if no one's tried it before someone must have the gear in their basement or something and able to try. If I don't hear anything, next hamfest I go to I'll pick one up for a dollar and try it on a strong station. Since low VHF is empty here, throwing that on the VHF side of the amplifier seems like a solution! Then again I'd hate for a 30 year old converter box to blow a capacitor and catch fire in my attic!
