The K9AY is RX loop antenna terminated by the resistor. This is ONE direction antenna. There is no directional switching relay. Impedance matching transformer is connected from one end of the loop to the ground and load resistor is connected the other end of the loop to the ground. Favoring signals are arriving from the feed point end. You can set different values by the jumpers. There is also common-mode current choke. This antenna is designed for SO2R or M/M setup - you can share this one direction to the more RX
