[TowerTalk] XM240 to Moxon

[Tim Duffy K3LR]

Hi Jerry,

Here are two mechanical designs for the 40 meter W6NL Moxon. Standard and
heavy duty.

The performance of the W6NL Moxon is very good. Good gain, good F/B and low
VSWR across the entire band - on a 22 ft boom. The Moxon's replaced
CushCraft XM240s at K3LR.

I have a pair of these two element antennas up at just about the same
heights that I have a pair of full size 4 element OWA Yagi's. 

On air comparisons show the OWA stack to have almost 7 dB more gain and 10
dB more front to back over the Moxon stack. This is what you would expect
given the element and boom size difference.

The Moxon pair has a little more gain as compared to the DX Engineering four
square that we use as well (expected).

A pair of two element W6NL Moxon's weighs about 100 lbs and the pair of four
element Yagi's weigh a little over 700 pounds...

73,
Tim K3LR

  I just read an article on the W6NL conversion of a XM240 to a 40M 
Moxon.  Anyone else ever tried this and do you have any comments, if so?
Tnx & 73
