[BC] FM Translator Co-location question

[towers at mre.com]

Unless both stations have substantially reduced vertical pattern antennas
and the distance between them is substantial (>10 wavelengths), this is a
bad idea.  The bandpass filters you need will never be tight enough to
prevent IM as some of the enrgy to be removed/filtered occurs within the
passband of the incidental transmitter AND the station's to be protected
transmitter. So there is in effect no filtering possible over 1/3 of the
passband on either station.

OF COURSE, YMMV and it's entirely possible it will work.  But I don't
think it will...
