Rabbit73's post just made me wonder something.

I have an Antennas Direct Combiner. Also located my second PA 18 preamp.

Would the Antennas Direct combiner work and not need the UVSJ?
I would put the Pa 18 pre amp on my VHF and eliminate the Winegard.

Here's what it says on the site:
This all-weather antenna combiner merges the signals from a UHF antenna with a VHF antenna on the same cable. Coaxial cable sold separately.
•DC Power Pass on UHF Port
•Insertion loss: VHF-IN/OUT 54-88 NHz 0.5dB; 174-216 Mhz 0.5dB; UHF-IN/OUT 470-698 0.8dB
•Return loss: IN/OUT 54-88 Mhz 18db; 174-216 18dB; 470-698 MHz 12dB
•Return loss: VHF 54-88 18dB; 174-216 18dB
•Return loss: UHF 470-698 12dB
•Isolation: VHF-UHF 54-88 30dB; 174-216dB, 470-698 30dB

Helpful Tips:

The DC power pass on the UHF port allows for UHF-only amplification in special circumstances. For example, when UHF signals require amplification, but the VHF signals may not. Or your household has an existing amplified antenna, but also needs to add a separate VHF antenna that doesn't need amplification.

It says diplexer on the picture

That is a UVSJ (UHF/VHF Separator-Joiner), which is also called a diplexer or UHF/VHF combiner. You can use it after the power inserter for the UHF PA18 or after the two power inserters for two PA18s.
