[TowerTalk] Balun question

I would not want an F connector on any of my TX antennas. I do not have any
RG11 however I thought that a standard PL-259 such as an 83-1SP fits that
cable perfectly.

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?
