This is very good advice, but it is likely to be PART of a solution, not
THE solution.
W2VJN's approach is not the best one. This is the best one.

Here's a practical implementation in W6GJB's contesting trailer.

We can run two 500W stations with K3 and KPA500 on adjacent CW bands
(80/40, 40/20) with antenna feedpoints within about 1 meter. Photos
show a tribander on a separate portable support, but we're now running
it on the pneumatic mast with the 40M dipole.

About a year ago I had a similar problem but with a K3 and IC-7600. I
determined that the main culprit was the RG-213 jumpers from the rigs to the
Hamation filters (also tried Dunstar 600's). When I replaced those two jumpers
with RG214 it got rid of most of the leakage, finally changed those two jumpers
to quarter inch Heliax and was barely detectable with either filter brand.
