[TowerTalk] Coax Options (for a 5,000 ft. run)

[Grant Saviers]

I suggest the stack matches at the tower base and stand up dog house for 
them. Thus inside storage of matches and the equalizing coaxial cables 
(100's of feet of hardline) so they are not on the tower, and protected 
from the weather.  Then a single coax and control cable for each band 
stack to the shack.  Having multiple radios on the same band at the same 
time on the same tower is probably not possible at HF.  Having each 
band's stack on a single run tower to shack permits SO2R or M/M 
operations on separate bands with adequate filtering and such is 
available off the shelf.
