[TowerTalk] JK 402 versus CC XM-240

[Tony Brock-Fisher]

I agree, SWR is not a measure of antenna performance. If a driven 
element is the wrong length, and you can match it with a tuner, you can 
still get great performance out of a yagi.

However:

SWR bandwidth is of great importance if you have to retune an amplifier 
when you QSY, especially on 40 meters, where EU stations often work 
split and your transmit frequency can go from 7128 to 7300.

With the 40-2CD, I would be nicely tuned up with 1500W out at 7130, only 
to see it go to a lousy SWR and the amp struggling to make maybe 800W 
out at 7283 without retuning.

So TECHNICALLY, SWR dosn't matter. But unless you have an auto-tune amp, 
PRACTICALLY, in a contest situation, it matters a lot!
