[TenTec] Antenna Problem

[Troy, W6HV]

Bernie,
 My old Mosley CL-33 has the same sort of balun at the feed point. However, I have added a current balun ( the kit from Palomar Eng.) where the feed-line enters the shack, just before the antenna coupler. My current balun is the double kit since I switch between several antennas including an inverted "L" for 160. All the antennas are overhead and none over 40 feet up. So far no problems with RF. Of course, as some have suggested, every cable of any type attached to the Orion II has ferrite toroids.

73,
Troy, W6HV

  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?
