Hello,

Yes, I've used it for FD antennas, 40 and 80 meters, as well as a pair of 
480 foot Beverages.  The Beverages presently are in use.  The Northeast one 
runs through woods so every now and then you have to go out and remove a 
branch from it and tighten it back up.

Noalox(?) is used with stainless steel H/W to secure the aluminum to the 
matching xfmrs (Beverages) and the 1:1 baluns for the FD antennas.  Even 
though FD antennas, theoretically, only have to last 24 hours these FD 
antennas have been used for FD for 4 years (96 hours so far!).  They 
resonant at the same freq. each year.
