microwave oven magetron + pringle can antenna
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: http://www.gallawa.com/microtech/mag_test.html 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?
