I'm one of the guys running two radios on one antenna. I'm using Yaesu radios
that have roofing filters. Into a trapped vertical. It works fine.

Subject: Re: [TowerTalk] Antennas for SO2R station
Can't really improve too much on what Steve wrote. I will reiterate that I
couldn't get a brand new IC-7300 to work here in my SO2R setup, (you can find
my review on eHam) whereas 2 older IC-7410's and a lowly , nearly
antique/classic IC-746 work just fine. (I do hear rumours that some folks are
using IC7300's in SO2R setups however)
My SO2R stn contains a mix of verticals and 4-squares(verticals) for the 'main'
radio (#1) and then a big multiband (horizontal) antenna for radio #2 (usually
the S&P radio) located 150-300' away from the other (vertical) antennas. No
stubs, no BPF's...cross polarization, good radios and antenna separation does
the trick.
I did it this way as I wasn't sure I wanted to invest a ton of money in 2 sets
of BPF's, a plethora of stubs, and a way to switch them all out back and forth
between radios. Certainly well into thousands of dollars. More if automatic,
tracking radios.
Am I the loudest stn up here? Nope.
Do I have good (cheap) fun?
Yup!

Just wondering if anyone uses 2 antennas on the same mast for SO2R?
---------------------------------------------------------------------
There are stations that go a step further and use the same antenna for
SO2R, with a triplexer (or even quadplexer). Of course, with a SteppIR you
can't do that.
If you are planning station changes anyway, my suggestion is to replace
the 7300. It's a great radio, at a great price, for a SO1R station, but the
A/D dynamic range limits it in SO2R applications. The 2nd change I would make
is to replace the SteppIR with a modern tribander and triplexer.
