Jim Seaton W1FWE presented how the em wave near and far field is developed from a dipole antenna, and propagates away at the speed of light. Jim also demonstrated, with an actual dipole, how relative polarity between transmitting and receiving antennas affects the received signal

Simple Loop Antenna for RDF
K1RMN Bob made a simple Loop Antenna for 2 meters.
1/4″ tubing , 1/2″ PVC tee and pl-259 ct. Made an 8″ loop , attached the loop ends to the cut away tee. Opposite side I cut the tubing and used shrink tubing to connect the loop together with a 1/2″ space. Connected it to the radio and listened to the Rason Vhf Uhf net and as I turned the loop the bull spot was 180 degrees out from the repeater direction. Works great.
