Hardware Overview
Radio Frequency Interface
The Radio Frequency (RF) interface consists of two QMA connectors on the faceplate labeled MAIN and AUX. Both antennas are mandatory; it both transmits and receives RF. The second AUX QMA connector is for the optional RX Diversity.
DC Power Consumption
The average DC power consumption according to the duty cycle is as follows:
