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.

Subject: [TowerTalk] 2 el 40m beams
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?
