Jeremy,
I have a MFJ 2 Meter Data radio on 145.010 at 5 watts on my packet BBS.
It has a Diamond F-22 20 foot to the antenna mount using rg 213 cause the run
to the shack is short.I use a Diamond X510HDN with a Yaesu
FT-8800R running 50 watts and the antenna is 30 Foot to antenna mount.
I use the
It would be interesting to hear how you would connect TWO 2Mtr. radios
(assuming a standard .600khz split and a single antenna connector on each) thru
a duplexer(s) to a single feed line and antenna. What type duplexer(s) are you
suggesting ? Have you done this before ? Just curious.

You could combine two close spaced transmitters using a
hybrid and the right combination will work through one
duplexer. Just throwing out one method...

Can't argue with you there ,but then he (you) would have to go into the radios
to split out the Tx and Rx from the single connector on the chassis. I didn't
think he was in to rebuilding the radios or spending alot of money.

The icom runs a max of about 65 watts but almost always less, more like 5 or
10. The antenna I hope to set up is a mobile 5/8 waxe over a ground-plane. My
purpose is for skywarn activations, as an NCO it would help to be active one
two frequencies nearly simultainously.
Any further help is
Where are your antennas going to be placed ?? On a tower , on pole mast, on
the roof, other ??? If i were going to mount 2 mobile antennas on a tower or
pole i would try to fabricate an aluminum plate groung plane and mount one
antenna on the top side and one one the bottom side then jury
Very difficult to guess with out some specific information so two answers

under the description you give you can put them on top of each other
separated by a 1/2 wave or better without any real problems. if you are only
going to transmit on one at a time then you wont have any reall issues.
You will be able to run up to about 25 W without any problems that I can
think
We will have other antennas side mounted but locked into 2 other positions (for
a total of 3 positions). Only one leg at the top can it be mounted on. The
mount is not far enough from the tower to consider a hanging antenna.
