The cable length between multiple cavities is predictable. As
an example between two notch cavities; the first notch
presents a very low impedance. With a quarter wave line to
the next cavity that low impedance is transformed to a high
impedance at the input to the next
to the transmitter that can sometimes cause the
transmitter to overheat or reduce output. Placing a cable of a different
length between output and the first cavity can sometimes change the unwanted
off frequency load seen by the transmitter.
