If you had been keeping up with the thread that was exactly one the
question that the OP was asking: could he parallel filters using coax
and tee pieces.

I have suggested a solution that only uses diplexers; the addition of
filters will probably not make much difference to the resulting
performance unless the radios in use have extremely high harmonic or
spurious outputs or produce very excessive wide band noise or there is
interference from 3rd party out of band transmitters. What will almost
certainly be more of a problem is the de-sense caused by the in-band
transmissions between the voice and data radios. Filtering that out is
not a trivial problem, at least at the spacings available at 2m.

I have been keeping up with the thread, Jeff. And he was asking about
using his diplexers. It was others who though adding filters would be
helpful. I have never suggested this setup.

But what is the suggestion you made? And how is it different than the
one I made? And exactly what is wrong with my suggestion?

And he was not asking about desense caused by using different radios and
antennas on the same band. Tom understands this.

But it seems some people keep wanting to to keep going off-topic with
extraneous information not related to the original question.
