Welcome to the sat world, lot's of fun. 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. Mike

I’m wondering if anyone has cable length recommendations for the M2 LEO antenna on a rotator.

I presume many people use a shorter length of LMR240 (or equivalent) and then switch to LMR400 (or equivalent) for the run to the radio.  So I am just trying to determine the length of those short jumpers at the antenna.

Would 15’ be a good length?

What 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?
