[Towertalk] GEM QUAD Separate Feed Info?

[wa7fab@cdsnet.net (K7VS Van)]

Have had a three element tri-band Gem Quad up for twenty years and fed with
single feedline.  Has anyone done the work on feeding each driven element
separately?  Would appreciate any information on coax matching sections for
each band if available.  Have no way to get up and measure each driven
element resistance on the tower and would very much like to feed each driven
element separately.  Thanks for any help available out there.
