Short answer: try the 4228 without the preamp; we've got some signals here too strong for the 7777 preamp and it's overloading.
I suspect that without preamp, and properly pointed, you'll get 10 (ABC 8 WTNH), 12 (WB 20 WTXX), 31 (Fox 61 WTIC), 35 (NBC 30 WVIT) and probably 33 (CBS WFSB) and maybe 55 (ABC 40 WGGB). Probably not 39 (UPN 59 WCTX).
You might also try internally switching the preamp to seperate UHF/VHF. Put a 75 ohm terminator on the VHF input. I expect you'll see significant overall signal improvement, but you'll lose 12 (WB 20 WTXX). Of course a separate cut VHF antenna specifically for 12 (if anybody still sells cuts) plugged into the preamp would solve that. But for 39 you'd need still another small antenna coupled.
Eliminating the preamp is not a great solution because a few of these channels need a little boost to stay steady through weather/Spring foliage/etc.
So my setup is a work in progress. Right now I'm without the amp and getting everything (including 39 from a second small antenna), but a couple channels only in the 60s readings (steady, not swinging), and ABC Springfield is in and out. I took the amp out because it seemed to overload when internally switched to combined UHF/VHF, though it didn't overload switched to separate UHF/VHF. Stark Electronics tells me it's definitely overload and a replacement 7777 amp would do the same. I'm still puzzled about why overload on _combined_ setting but not _separate_, but he seems to know what he's talking about.
Among other things I'm going to try is to put a UHF/VHF splitter right at the 4228, run seperate UHF and VHF lines into the 7777 amp (obviously switched to separate UHF/VHF) and see if the signal comes out clean.
