Radar Class
(2)
My experience as a radar maintenance technician in the USAF serves me well when it comes to formulating a theory of what is happening to me, radiation-wise. I remember that one of the warnings regarding radar transmitters was that it was not a good idea to stand in front of an active radar antenna. But the antenna is only a reflector, shaped to beam energy of a particular frequency. Different frequencies require differently shaped reflectors. Lower frequencies cannot be 'beamed' unless the reflector is extremely large. Lower frequencies can be beamed (more or less) by a dipole antenna fitted with 'directors' and 'reflectors.' Hence the many elements of the old-fashioned TV antenna: there is one active element, and the others are either directors or reflectors. The active element in a radar antenna is the feed horn: microwave energy exits the feed horn and is reflected into a narrow beam by the reflecting antenna. The beam is pulsed. This pulsed energy is reflected by objects (such as airplanes). Returning energy is reflected by the antenna back into the feed horn. This minute amount of energy is then directed into amplifiers and displayed on radar sets. Then the next pulse, and so on. The higher the frequency the smaller the reflecting antenna. A reflecting antenna must match the transmitter frequency in order for a beam to be produced, otherwise the radiation pattern is not a 'beam.' Got that? A beam represents the highest possible concentration of energy along a single path. It is sort of like a flashlight beam. The same reflector can both transmit and receive efficiently, but only at a certain frequency.
My conjecture is that 'they' are beaming powerful microwave energy at me using small reflectors (like 'dish antennas'.) These beams are quite narrow, about 15-30 inches in diameter. They may be able to focus these beams by changing frequency slightly. The wooden construction of the building does not significantly impede this beamed energy. My primitive attempts to deflect or absorb this beamed energy before it reaches me are unsuccessful. I don't really understand the physics involved.
The transmitter frequencies are most certainly above 5GHz, because my ZC-185 can't detect that energy, which must be above 5GHz. (Compare 5GHz with 2800 mcs, the CPN-18 frequency, and 9080 mcs, the FPN-16 frequency.) Whatever. The problem is this: how to account for the wide range of symptoms given the narrow band of possible frequencies?
