[TenTec] Antenna Problem

[K5XS at aol.com]

Ten Tec Friends,
 
My new Orion-II adapts well to a high SWR with its built-in tuner (it  really 
does work nicely), but tomorrow I will try to eliminate one possible  cause:  
The feedline.  I can do that without lowering the beam.
 
Has anyone on the list used a current balun?  I am using a Cushcraft  A3, and 
Cushcraft has you wrap several turns of coax in a coil to keep RF (I  assume) 
from coming back down the feedline.  I was hoping to eliminate that  bother 
by using a current balun. Has anyone done that with success?
 
73,
