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

There seems to be quite a lot of material on the web for this topic
and I suspect some practical solutions. Also while perusing Usenet
archives on another topic I found this list from a french newsgroup
which may be useful if the links haven't succumbed to bit rot
(haven't checked them):
