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.

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?

Bernie K5XS
