Directional antenna D6656 is used with antenna distributor D6657 to increase receiving distance. One distributor could be used with 4 receivers simultaneously.
If you only need to enlarge the receiving distance of 1 receiver, you can connect the directional antenna to the “ANT A” terminal and “ANT B” terminal of the antenna distributor. However, the receiving distance is less than the receiving distance of connecting directional antenna to antenna distributor.
The active directional antenna need to be aligned with the direction of the microphone.
Antenna distributor can supply power for receiver.
