One microwave oven magnetron will get you pretty close to the legal
limit. They can be injection locked together, but that usually requires
a circulator that can handle the necessary power (big $). You also need
some way of adjusting the phase between the magnetrons so that the power
will add. The adjustment can be tricky as they will tend to interact
even with the circulators.

Does anyone in the group know anything about magnetrons? I planning to
do some experiments in transmitting microwaves.

I would like to use standard magnetrons from a microwave oven and
believe I can beam further if operated at the same frequency and
with the outputs in phase. I have no idea on how to do this. Please
advise
