I would imagine you might want to bid on 4 that I have belongs to a
radio club in northern Ohio - they paid 800 bux and they worked good
until we split the site with the solid state pa deck. There is info on
adding a pass notch out of cable to the inside somewhere on the web, I
wanted to try this and the following year that tower was destroyed by
mom nature. If you go with steel they need to be plated nickel to fill
in the voids and then polished to minimize loss, copper would have been
a better choice but with the EPA action on cyanate electroplating you
would be money ahead to just buy new cavities for you freq. at 4 or 5
grand US. If you want to talk about the cans email me off list and
include your callsign in the subject line - if no callsign I just dump
like spam.
