Topband: ?? abt shunt fed tower

[Lane Zeitler]

Gents,
A friend of mine here in San Diego wants to shunt feed his 50 ft self 
supporting tower. Not much on top of it except a Cushcraft A-4S with the 40 
meter add on kit. reflector and director are attached directly to the boom, 
not insulated. I will be doing the manual labor for him since he is getting 
up in years and not able to do the work. How far up should I attach the 
shunt?? There is a pipe abt three feet above the tower at which point the 
beam is bolted. Can anyone give me an idea?? I would rather not just 
randomly pick a spot.

thanks

Lane Ku7i
