Congrats Ron! You will really like this antenna!
We used a stack of these antennas during the past 4 DX contests for our 40
meter second station and they worked great!
For those wanting the conversion document (CushCraft XM-240 to W6NL -
Moxon), it is available on http://www.k3lr.com Click on STATION ENGINEERING
- then 1st topic.
73!

Full-size Moxon is finally up and installed on the KC5FU Contest Station
Multiplier Tower.
I think some of you had questions after it went up, but I don't recall who?
