The stuff finally all came in the DB8e lagged the rest by a week or more.

ADT you were right - the CC7870 was worse in this application.

The good news is that the Y5-7-13 and DB8e with the diplexer (a blonder tongue UVSJ) did the job. I put the VHF antenna 30 ft ENE of the DB8e to minimize any crosstalk issues. Both antennas are in the attic of a ranch house, about 14 ft AGL.

No amplifiers or other tricky bits were needed.

I get all the way down to 13.4 NM on the list, which is everything I wanted and more. All channels are above 25 dB SNR on the diagnostics screen, except 9.1 which is a marginal 21-22. If I have trouble with 9.1 I'll spring for a slightly bigger VHF antenna.

I don't know why I have issues with 9.1 at 50.2 NM, when I can get KTSC-DT ch 8.1 at a NM of only 13.4. Perhaps my TV has very poor sensitivity on that one channel? I can't picture it being an over-driving problem, but I reckon it is possible. On second thought the mis-tuned rabbit ears would have precluded any overdrive issues, so I'm back to poor sensitivity at that freq. Spurs in receivers are not unheard-of.


Thanks,
Don
