That makes things more clear now. I had ordered an extra HLSJ anyway. So I will need to cut that in ahead of the UHF outside that weatherproof amp enclosure and protect with mastic tape, a pain yes, but doable. What I need is decent weather.
Antennas - well... the UHF is a DBGH20 optimized for max gain on 34 with a null for 14 at the rear with gain lobes for 17 & 22 at the rear, so I can only have one UHF and get signals in both directions. The UHF is a GH6. These are of the 4NEC optimized optimized type via nikiml's site.
