And that was the kind of thing I was referring to. I saw a mobile mount that used some small diameter heliax (about 1/4") from the antenna to the radio. I immagine it was for 800-900MHz or something like that.
Basically, I was just curious as to how common and/or practical it might be. In a large vehicle, with long coax runs, I could see the benefit of small diameter heliax. especially at higher UHF frequencies. I could see it being practical in an RV, or commo trailer/van. I just didn't know if it would hold up mechanically. (....kind of going back to that solid vs. stranded center conductor argument for mobile coax installs) Thanks for the input guys.
