[CQ-Contest] Stubs are not a joke

[Scott Robbins]

I have been doing some work on a SO2R contest station and have only
recently come to the question of using band stubs for nulling out
unwanted signals.  I have noted that at 500 watts I don't really have
a problem, but at 1500 watts it starts to present a little bit of a
dilemma on a few band (but not all) combinations.

I understand the generalities of using stubs, but this is one question
I don't know the answer to:  is right at the output of the amplifier
the only spot the stub is useful/usable?  I use a couple of mono-
banders on a remote coax switch that could easily have stubs on T
connectors added at the switch.  I have seen nothing to indicate this
is indeed possible, but wanted to inquire with the thought pool
here first.
