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).

I had a lightning hit.Not bad but somewhat costly.A rcs-8,cde rotor box and a cushcraft ar270b.Seems to have hit the vertical as all coils are gone incliding the base matching.The tower is down for repair.At this point I am bringing the coax down the tower.The switch had been at the top with one feedline.The feedline was run outside the tower with coax stad-off.rotor and ctrl lines inside the tower.So my question to the group.It is better,or worse for the coax to run inside or outside..73 and in advance,Thanks to all...john W5JMW
