Not sure about those Omni directional antennas, but the double bow ties are geared toward UHF mostly, unless you're pretty close to the transmitters.
I've installed a few of these https://www.solidsignal.com/pview.asp?p=HDB4X
BUT they always have trouble with KABC, KCAL, KTTV, and KCOP because these stations are H-VHF.
Sooo we've had to install 2 antennas (one larger VHF and the HDB4X) and combine them into the RCA pre-amp to receive all UHF and VHF stations. Without the separate VHF antenna, you may pick up H-VHF stations at certain times of the day or year but it can be frustrating when you're wanting to watch/record a show that starts at 8pm and then the station drops at 7:30pm!
The HDB4X's frequently go on sale for $24.99 at Solid Signal or on Amazon.
I've installed 3 of these in Claremont, Los Angeles (Griffith Park area), and Ontario.
The Ontario install has no problems with H-VHF because it's pretty much LOS.
The Claremont install has issues with KABC and KCAL. (I'll be adding a small VHF antenna to this one this week.)
The Los Angeles install has issues with KABC and KCAL.
As far as solar panels, I can only speak for myself. My neighbor behind me one door down has panels directly in my LOS to Mt. Wilson. Late in the afternoon KABC and KCAL seem to drop out. Not sure if it's his invertors or panels or just a low freq. interference...?
