Good question--- The Hustler is via 1/2" heliax, the other two are 9913 or LMR-400 or maybe one of each----I'll have to look later today when I get over to the site. It's all on the roof of a 6 floor Hospital-----super intermod city! The Hustler was installed as the repeater antenna----the other two are normally used for remote base linking----I'm aware of the general no-no concerning foil coax's in duplex service.
