Human body effects at 184MHz
At 184MHz an adult person walks toward and then away from the antenna mounted 1m above ground. Standing behind the antenna i.e. not in the direct TX-RX path. Total distance toward and away from the antenna was 10m. The variation in received signal is about +3dB and -3dB with respect to the received level without any human body interaction. NB the human body acts as a re-radiator (and absorber) at 184MHz and, as can be seen, it can act as a good reflector at certain distances from the driven antenna, increasing the signal amplitude at the receiver. Conversely upto 3dB loss can be induced by the same mechanism.
