[TowerTalk] JK 402 versus CC XM-240

[john at kk9a.com]

There is no question that the 40m Moxon is a great design however it is 
not a small 40m beam and as you mentioned it can be difficult to 
install. Side mounting them might be a real challenge. I wonder how the 
Moxon gets along with other antennas?  From my NEC2 model (which is 
inaccurate for this design) it appears to be resonant on ~27 MHz.

As Grant indicates, I use two W6NL Moxons at 8P5A.  They are on 
different towers and are not phased.

Overall, I could not be happier with them.  While I do not have an 
antenna testing range, they seem to have a discernible pattern across 
the whole band an have an SWR below 1.4:1 at the band edges.  I seem to 
be able to work people with them

The prior antenna was a 3L Hygain that I struggled to keep working.  I 
took the driven element down at least 30 times.  Plus, it was not clear 
how broadband it was, either in terms of pattern, and certainly not in 
the case of SWR.

I can’t speak to the JK antenna, but the W6NL has held up well so far in 
a very corrosive, but no ice environment. With the Tbars it is not an 
easy antenna to install without a crane.  Twisting it up through the guy 
wires was extremely difficult and required some steps I would not 
recommend.

Thanks to W6NL for his technical contribution
