fluctuating multipath; need solution

I installed a new Winegard HD-7084P antenna months ago. Now I have frequent dropouts ("no signal" on the TV), which I'm pretty sure are due to fluctuating multipath.

7084P sounds good, but in the Los Angeles area there's a lot of low VHF which will be picked up by it. I'm wondering if that will disrupt the converters.

On the other hand the 7698P doesn't catch...

Funny! :)
When I entered "not channels 3,6,8,10,12. no analog stations" I meant that I'm not interested in receiving these. Of course there's no antenna that will reject them!
