Loss in coax is not an issue if we're limited by RX noise. It only
matters when where we live is very quiet. I use Commscope flooded RG6
extensively for RX antennas from 160 up to UHF
Good luck with that voltage breakdown rating for foam RG6 running high
power through it and other than a flat line.
As to the milliwatt loss on transmit, okay FB but on rx with
microvolts, I'm already deaf and don't need for it to be any worse
than it is.

Point well taken, Jim! I actually use a couple different

WRONG! This may be true of SOME RG6 cables, but definitely NOT true of
many.
For at least 50 years, RG numbers have not been a spec, but rather a
general description defining impedance and
I can testify that F connectors with RG-6 will handle the legal limit on at
least 160 and 80 without even getting warm.
This is true here with 2500 watts into a dummy load and CW contesting.
I waterproof mine by partially filling them with silicone dielectric
grease. Been doing that here for many
Greetings.
I do not know if they still do use them.
But the MAJOR Amateur AND PROFESSIONAL antenna maker M Squared uses "F"
connectors in their antennas ALL the time.
They even use a variation that is weatherproof.
They use them from below 1 meg antennas up to antennas in the Gig
ranges. Mai
Colleagues,
I was very happy to see the discussion regarding the use of television
feedline and F-connectors. I thought I was the only ham in the
universe using that combination. While it's true that the connectors
are not weather-resistance, a coating of black asphalt sealant* takes
care of that.
