The DB8e is an excellent antenna. It's not deaf to VHF, but that's outside its target bandwidth. NB the DB8e and DB8 are different antennas.

WXIA is quite strong; I'd expect you to pick up WXIA...

First, you have lots of signal in the air. Likely the rabbit ears would work for all the green channels in the 228 compass heading direction IF there were no other sources of interference. Once you...

Two brief additional comments, if I may.

More vertical distance between the roof and the antenna may help. Electrical coupling to the roof could be an issue.

Oh! That's quite a nice TVFR. Do have a clear aim to the horizon at compass 190? Very few stations on your report are not at that heading, and almost all of those are impossibly weak. And one KCHF is...

I don't think there's much good news there. 10' is pretty low, and there are not a lot of strong stations in your vicinity. There are quite a few stations at ca 30 magnetic, but many of them are...

Hi -

If you can aim between the trees at 179, then the UHF stations in that direction should be easy. The two VHF-high stations on your list are also at heading 179, KGO and KNTV. I'd think you...

Each real channel has one or more virtual channels multiplexed into the signal. Usually that means one HD channel and 2 or 3 SD channels, although I receive two RCH that have 4 SD VCH on them. I...

You are fortunate that all the stations of interest are broadcasting toward you from Mt. Wilson.

Try taking your antenna up on the roof first. Installation in an attic is a significant handicap.
