I wonder if anyone is doing anything similar for the Force 12 
EF-240S/C-4XL/C-4 series antennas -- anything that uses the EF-140S 
dipole.  It strikes me that substitution of coils (plus cap hats?) for the 
current linear loading could be a real plus in "plug-and-play-ness."  Best 
would be different coils for the reflector and driven element, so that the 
element construction wouldn't have to be messed with.  I assume that a 
Phillystran truss using the existing uprights would be a necessity if this 
were done.
