That's exactly what I'm doing. VHF GE mastrII at 100 watts goes through
2 8" Sinclair pass cavities set at .5db gives 80 watts to the antenna. 4
bay exposed dipole at 75' The receiver and preamp goes through only one
8" Wacom also set at .5db then up to the collinear receive antenna at
100' Very very little desense almost undetectable. Also with the pass
cavity on the receiver side preamps seem to be much more usable and
effective in the real world. This machine hears very very well! More can
be seen from my website. www.kc7rjk.net <http://www.kc7rjk.net/>

Subject: [Repeater-Builder] Antenna separation question
Ok just kicking this idea around the other day and the question came up
about antenna separation. I know the basic 2 meter antenna separation is
50ft. (I am thinking 60ft to be safe) But is it possible to get them
closer if I place some cavities on either the receive or transmit sides.
Sounds dumb from some certian points of view, but I am waiting on the
arrival of a decent duplexer (could be some time out though)so in the
mean time I would like to get this up and going with a split antenna
system for now. I was thinking maybe a 30ft separation... Would this
idea work? If so does it need to be modified from what I was thinking?
