That's why I say, "Purchase and use the largest coax you can afford"  
The DC resistance will be lower than the regular cables used so it will 
excel at low HF, and the dielectric will be less on higher frequencies.  
I'd use all 7/8" Heliax with the copper tubing center conductor, except 
there are over 12 connectors in each coax run. (I can usually get the 
cable cheap or free)  It's bad enough at $13 each for crimp connectors 
on LMR-600, let alone the ones for 7/8".  Sure you can sometimes find 
pull outs and I'd still need to use pigtails on each end, but hauling 
that stuff to the top of the tower is *work* <:-))
