[TowerTalk] Balun question

[Steve Maki]

Carol,

Your first question was not clear - is it RG-11 style or hardline coax 
that you have?

If it's RG-11 braided cable you should take the suggestions and replace 
the F connectors with PL-259's. If it's solid aluminum hardline I'd 
still replace the F connectors, but you'd have to use one of the many 
DIY methods that have appeared on this reflector over the years, none of 
which is as simple as a PL259 on an RG11 cable, but not very hard either.

73, Steve K8LX

When I want to go on SSB, I usually run the coax through a Palstar AT2K tuner. I never worried about this before since I always used coax chokes, but now I might have some concerns. Although the amplifier ( 1kw) is happy, SWR-wise, I realize that I might have some high voltage that might be going through the chokes and ultimately fry them. Any Thoughts out there?
