A few years back I saw an excellent presentation by Ira K2RD on the
measures he took to isolate two radios simultaneously driving the
separate feedlines of a Gem Quad. You might contact him.

>In the recent NCJ article by K0SR about Quad construction, he mentions that
the best way to feed a quad is to feed each band independently and use a
switch mounted on the mast to select bands. Has anybody used a triband quad
on 2 bands simultaneously (obviously with proper filtering)?
