I remember back in the 70's we had radar sets with ZERO volts on the

I haven't done anything with radar in well over 30 years, so I don't
know if they still do it or not. But I wouldn't be surprised. At first
glance it sounds crazy - but it made for a very simple and efficient way
to couple the output of the magnetron to the waveguide.


Microwave ovens still do that. At least, my Toshiba does.
