Jim;
I've been using the INRAD Triplexer with switchable Dunestar filters on
each radio for about a year now and have been happy with the results. As a
low power contester with a single 4 band yagi, it's almost like adding two
additional yagis to my station. I get a lot better results with SO2R now
than I did using a vertical or dipole on the second radio.
You do need to be sure you have low SWR on all 3 bands and, of course, be
sure to use some type of bandpass filters with them.
I did notice that the attenuation on the direct harmonic band near the
harmonic frequency was not as good as I would have liked (i.e listening on 10
while transmitting on 20). Other than that, this setup works great.
If interested, I did a short article on this in the TCDXA Newsletter at:

See Page 5.
Good luck, Jim.

I have the good fortune of needing to acquire an HF triplexer for the
upcoming WRTC2014 in July.
I know of Inrad and Dunestar (plus the 4O3A high power one, which is out
of my price class). Any others available in the market? Does anyone have
any
experience or other informed opinions on this subject?
