[TowerTalk] Andrews 1/2" Heliax Connectors

[J.Hector Garcia M]

use the  original superflex N connectors , later if you want to convert to
UHF , use a piece of lmr 400  with ferrite beads like a line isolator  with
a good quality connectors , good weatherproof and you are done. i do this
and have no problems. using the hard lines 7/8 , 1/2 to my antenna switch
and radios.

there are several ways to keep this at low price, surplus sales of nebraska
,  palomar engineers, and e-bay..
