Cool!

...and now a for the more mechanically minded among us;

I'm thinking of using a 1" diameter solid fiberglass rod to insulate the 'SigVectalute IV,ooo' from the mast by installing .1875" wall, 1.375" diameter, mast section 12" into the bottom then cutting it off as it leaves the base of the aluminum antenna and adding a 14" piece of 1" solid fiberglass rod about 6" into each mast half as an insulator, exposing about 2" of fiberglass rod at which point I'll have the coaxial common-mode-current choke and an RF isolation coil in the DC ground wire. That is as much RF isolation as I can figure out how to accomplish.

I'm wondering if 1" fiberglass rod would be strong enough to support it in ~60mph wind?

- It seems strong enough to tow a truck but I just don't have the experience nor FEA info to know if I'm 'setting it up for a fall'.

Anyone have experiential / empirical knowledge of the strength of 1" solid fiberglass rod, especially within this type of application?
