What antenna are you currently using in the attic?
Do you have to move it around to get all your channels of interest?
Hello,
Yes I was reading about other amps better for higher-signal areas. I saw that there was also a 7778 which is suitable for medium to strong areas when there is a distribution to feed through. I had heard good things about the low-noise characteristics of the 7777, that was why I figured something along that design might be beneficial... But Im all ears.
We could get all channels well it seems with the RCA amplified rabbit ear setup (rabbit ears and a UHF ring in the middle). However the amp needed to be turned all the way up. Sometimes adjustment is needed, seemingly weather dependent...
If I could get "virtual channel" 3, 6, 10, 12, 23, 29, 52 that would be great. The only ones that are not UHF are 6 and 12. We have never been able to get either on rabbit ears anyplace but up in the attic... But when up there, it works OK.
Something like the 7778 would let me make a twinlead dipole like this:

and then get a good UHF to combine in and be OK, it seems to me (maybe Im wrong though, trying to learn). My attic is walk-up and finished (80 yo home, all wood), but I have space between kneeling walls which lets me install antennas high and out of sight. I can put the UHF in one wall and the VHF in another I suppose if need be.
Thanks very much for your help!
