I only operate RS-44 due to a high noise level on 2 meters. I would recomend a preamp for 435. It's a big help. The radio uses Pl's on 2 so I would not worry about that. Good luck see you on RS-44.

So I am just trying to determine the length of those short jumpers at the antenna.\nWould 15’ be a good length?\nWhat about connectors? For UHF side I will use N on the coax. On the VHF side, instead of a barrel adaptor connecting two PL259s, would it make sense to go VHF antenna -> PL259 - coax jumper - female N -> male N - coax to shack - male N -> female N - coax to radio - PL259 Or is it fine to leave them all PL259 / SO 239?\n73Erik K2ERK - FN20\n\n-----------------------------------------------------------\n\nSent via AMSAT-BB(a)amsat.org.
