[TowerTalk] good,bad,ugly opinions on coax in or out

[Grant Saviers]

It seems logical to me that coax inside the tower is less susceptible to 
RF noise pickup as well as somewhat protected in a strike by the tower 
as a Faraday shield.  What is most important is the coax bonding at the 
top and as close to the bottom as possible. Inside is probably very hard 
to do well on a crank up, easy on a guyed or freestanding tower.  The 
cell tower accessories for coax and cable supports mounted inside a leg 
are cheap and also keep the face a bit more clear for climbing but won't 
work on a crank up (maybe somebody has figured out how).
