This module is a must-have for the subscriber that demands accuracy in steerable antennas for directional antenna pointing. With high-gain directional antennas having a narrow main beam, it is imperative that the steerable antenna be pointed directly at the target station for maximum signal strength. This module also goes nicely hand-in-hand with module INT004 – Lookup Box which takes for input the target station’s callsign and among other provided data, gives the azimuth in degrees to the target station for inputting into the ATC004 – Antenna Rotator (micro) module. A very nice combination for sure!
