[TowerTalk] 2 el 40m beams

[GALE STEWARD]

I've have had very good luck with a reinforced Cushcraft 40-2CD. This antenna was reinforced as per the W6NL mods and has survived ice, heavy wet snow, and high winds. The newer model CC XM-240 can be strengthened in the same way.

Mine is at 72ft so yours would see a bit weather related stress at 100ft.

Also, if you want full length elements, ON4UN's 3 element 40M yagi looks very strong. With a bit of computer modeling, you could re-configure it as a 2 element antenna. John's elements & boom are very robust.

GL with the project.

Hello out there.

I'm at a loss as to what to replace a snow-damaged 2 el 40m beam with. 

Everything I've found on-line doesn't really call out how strong the antenna is. 

Ideally, since most "gain" figures would be nebulous anyway, I want the STRONGEST beam 
out there since it's going on Bertha at 100 feet.

Any suggestions?
