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.
