well for one we know the frequency inside the cavity is double that of the pulsing frequency.
and to outlaw:
i don't think that is the case at all......these waves do not have the power to interfere with such signals.......nor do the frequencies leave the cavity which will act as a cage in shielding......there is another reason why they switched from analog to digital though......digital can be monitored down to a single home and which homes are watching what.
look:
http://www.youtube.com/watch?v=WkNlivEtUag&feature=channel_pagewatch all his video's, it's based on frolov, avramenko and strebkov. possibly it's all standing waves with non moving changing voltage, pulling energy from he environment like in this video, disrupting radio signals. something like that.
Here the same circuit is used on a WFC with positive results, also standing waves I believe, but haven't looked deeper into in, so it's a guess.:

standing waves in a light tube, can it be compared to plasma longitudinal waves as described on wiki?
