Topband: TV coax + F-connectors

[Joe]

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. Mainly at the feedpoint to connect the phasing line in the 4 to 
1 balun feed design.
