[TowerTalk] Discoverer 7-2 or Cushcraft xm-240

[Tony Brock-Fisher]

I have to second what Paul, W0AD said about the W6NL Moxon. I replaced a 
CC shorty-forty with the Moxon design and the difference is NIGHT AND DAY,

-For the first time EVER, I find a frequency on 40 (never a 'clear' one, 
just one where nobody comes yelling in your face to QSY). I call CQ for 
10 minutes, and I notice that the frequency is getting QUIETER! Folks 
are moving away from me because I am LOUD.

-The SWR is much better than the shorty-forty. Even with 'secret' 
compromise settings, the shorty-forty will be over 2:1 when you go up 
high in the band - such as operating split in a SSB contest. With the 
Moxon, the SWR is below 1.5 anywhere - no need to retune the amp.

-There are no coil losses. Talking to W1JR, the coils on the 
shorty-forty are lossier than you think - as the bandwidth is wider, so 
the Q is lower, than predicted by modeling.

-The elements are longer, so they have more directivity in and of 
themselves. This adds to a better pattern, more forward gain.

All in all, between the coil losses and the directivity, I'd say it is 
~4 db better than the shorty-forty in forward gain. That's a lot on 40m!

Contact me off-list for details. I built one from scratch and would do 
it again in a heartbeat.
