[TowerTalk] KLM 40M-2B Opinions Please

[jeremy-ca]

I've been contemplating supporting the elements also but not with 
Phillystran. Instead I would use some #14 hardrawn copper and wind up with a 
2 el on 30M. I havent modeled it yet to see what spacing I'd need to 
minimize interaction but the concept intrigues me.

You could also do away with the weight and wind loading of the linear 
section and use coils as in the Cushcraft. Thats another idea Ive got 
working as I was given 2 CC coils from a crashed tower to experiment with.
