Stuart, this was an interesting post.
The power part was a no-brainer but the dual-shielded coax is something I
haven't tried in that environment.
I would be interested in knowing what kind of radios you guys were using and
if in the process you had to rule certain models out because they crumbled
in that situation.

Lowering the contest power to 100 watts greatly mitigates possible inter
station interference.
We used double shielded coax this year which allowed 3 100 watt stations to
have 3 coaxes run together to exit the room at the same window. I did not
expect it to help all that much and was using it for the pre made lengths of
it I had. Only if the 20m phone station got very low in the phone band did
the nearby CW station seem to desense the receiver. That was a simple QSY
to fix. No band pass filters were used. Antennas were a vertical against a
inverted vee about 125 feet apart.
I am certainly glad I had the chance to use double shielded coax.
The vertical had a tuner at the antenna with remote cable control, and the
doublet had a coax choke at its feedpoint, of RG8x
