[TowerTalk] 40 Meter Yagi

[Steve Bookout]

Joe,

A couple of years ago, I built 4 Moxon's for 40, two for me and two for 
a buddy (actually, he help quite a bit) and could not be happier

The boom is 21 1/2 feet as I recall and I know the elements are short, 
but don't remember their actual length.
I went with the Moxon design because of the f/b ratio and the 
bandwidth.  Bottom of the band is 1.4:1 and the top is 1.3:1 and flat a 
7150.  Gain is typical of any 2 element antenna at 6 or 7 db, but the 
f/b is about 30 db instead of 12 db, or so, with the standard 2 element 
design.
i do not know of any commercially available, but many have been made 
using 2 element Cushcraft antennas.  Lots of info on the web.
I could not be happier with it.

I don't want to re-ignite the Moseley wars, but I would be happy if someone could point me at an a 40 meter beam that might be able to fit on a city lot.
