I would think a 1KW or greater magnetron run off a non-filtered and
particularly dirty, but rectified dc supply (you could even feed a ramp
or triangle dc power wave to the magnetron to cause frequency sweep) and
into a sloppy waveguide exhibiting multiple resonant frequencies would
knock out all cell phone and wireless communications on shf+ freqs for
blocks if not miles... you would probably start jamming the cell towers
for miles around and have every "pirate transmitter" hunter in America
on your tail... in a large city/metro area you would cause havoc to
break out--this WOULD BE ONE SERIOUS OFFENSE!!! If caught, you would
learn to call prison your home!

And Bruce, in the cell next to you, would fall in love with you!

Not to mention the danger of exposure to the freqs in question--this
would be best left alone...

Any suggestions on how to build a 2.4 GHz CW transmitter with a
microwave
oven magnetron and a 2.4 GHz "pringle" or coffee can style antenna?

There are tons of "pringle" or coffee can antennas or similar on the
web.
For example: http://flakey.info/antenna/waveguide or
http://www.turnpoint.net/wireless/an...coffeecan.html

I suppose one need only insert the magnetron antenna into the coffee
can
where one would normally mount the N-connector feed point.

A labeled diagram of a microwave magnetron can be found at:

I suppose the metal coffee can has superior micro shielding properties
relative to the aluminumized cardboard pringle can.

Would I be better off with plumbing copper drain pipe from the stray
RF
exposure perspective?

Since microwave magnetron use a half wave power supply, can I use two
magnetrons in the same coffee can powered from a single AC HV
transformer
with a pair of HV rectifiers to feed alternate cycles to the
magnetrons?
