[TowerTalk] coax and leaks

[Grant Saviers]

"poor coax is like carrying water in a sieve"

Braid coverage matters.  Commercially double braid or hardline (solid Cu 
shield) is used for jumpers.  For hams, the RG8 size "foil plus braid" 
is the economical choice if from a reputable brand/supplier.  DXEng also 
sells double braid TFE mini coax jumpers which, while expensive, are 
very handy for rig to amp to filter jumpers.  Or buy the bulk RG400 
(stranded center) or RG142 (solid center) TFE silver plated double braid 
and make your own.
