[Amps] Coax question

[rick darwicki]

Hi all,
 
My Alpha has some unmarked short coax from the PI network to the relays I'm replacing with Gigavacs.
 
I need some small coax and have RG-122 that I think will work for the input side.
 
Any suggestions for the high power side? These are short 6-8 in pieces. 
 
Thanks

Rick, N6PE
