[TowerTalk] Balun question

[CAROL RICHARDS]

Hello all,

I have two questions which I hope someone will be able to answer...


1. I have acquired a large supply of 75 ohm ( aka RG 11) CATV hardline from the local CATV company. They were even kind enough to install the F-fittings for me. I have enough F-PL259 adapters to use with the cable. Will the CATV fittings handle 1kw on 80m and 40m inverted vee's?

2. I built several 1:1 Current Baluns from the April 2021 issue of QST and they work fine. The specs say they will handle legal limit. Both my 80m and 40m vees are cut for CW. 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?
