[TowerTalk] 2 & 3 el 40m Booms

[Dan Hearn]

The latest ARRL antenna book has complete info for 2 and 3 el 40m beams on p 
11-23. There are graphs for gain, f/b, and swr as well as mechanical design 
details. There is taper, diameter, and wall thickness for elements and 
designs cover different boom lengths.

thanks mike.

i was looking for a bit more specificity. tubing diameter, wall thickness, 
taper schedule
recommendations.

something reasonably sturdy, knowing FEW THINGS will survive a hurricane.

Scrap antennas (I've picked up some off the auction site), old
antennas that didn't work well, aluminum from Texas Towers, EMT from
the hardware store, only wire (had a 20 quad with eight elements
once). Lots of things.
