[Antennas] Antenna SWR

[David C. Hallam]

Don,

I guess the SWR table I copied in my posts was stripped out by the 
system as I didn't see then in my email from the reflector. Anyway I am 
using a Kenwood TS-130 transceiver which will start reducing output if 
the SWR goes over 1.5:1. That means an antenna tuner which I don't want 
to mess with.

I normally use a Johnson Invader 200/Collins 75S-3 set up. I guess I 
will just have to go back to it. The Invader doesn't care what the SWR 
is. It will load a wet string.

Many just drive a ground rod into the ground since the SWR is better, happily assuming that is the best and most efficient antenna they can get.  Or settle for a couple of ground radials because SWR rises as they add more.
