Hi Al.
We actually have done this very same thing on a local 220 Mhz
repeater. The repeater's SAV 15 PA runs much cleaner maxed out so we
run it full blast and cut it down doing just as you suggested before
feeding the outboard PA. I think that we ended up with 70 some feet of
RG-58 in an aluminum box with connectors on it. Work great. My problem
is space. I have to have three attenuators in one rack so space is at
a premium. I can take the small BNC type and shave off the excess gain
right at the pre-amp. With all of the responses I may have found just
what I am looking for.
It would be neat to find some high quality pre-amps that made only
6-10 db of gain just to make up for small losses. Most are anywhere
from 10-20 or so. Too much when you just want enough to make up for
the Rx splitter and some cable loss.
Thanks to all that replied to my original post.
