[TowerTalk] LMR-600UF and variants

[Mac]

I have and continue to use this same RFS cable Peter mentions and it is 
near flawless,  and my application is i have 4 runs at 100' + in daily 
use on a 589 crank up tower and including the radial loop between mast 
and tower tie point, i dont change to any other type feedline direct 
hook up to the antenna or balun all the way.. connectors are easy and 
reasonable in cost...
