[TowerTalk] Heliax Connectors

[Ryan Jairam]

Unless someone is running at least 3x the legal limit, I doubt any
amateur running legal amateur power levels will have any problem with
either an N connector or PL259. Andrew N connectors can actually
handle up to 10kW (peak) according to the spec sheets.

High SWR may be a different issue but I try to avoid high SWR here.
The only antennas I have that routinely operate under high SWR are fed
with 450 ohm line.

Anyway, my whole reason for using N was availability and cost.
Performance is a non issue because under HF amateur applications at
legal limit or less into a 50 ohm load there won't be any difference.
