ANTENNAPOWER

Controls power to the antenna

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700

This command enables or disables the supply of electrical power from the internal power source of the receiver to the Low Noise Amplifier (LNA) of an active antenna. Refer to Antenna LNA Power for further information about supplying power to the antenna.

There are several bits in the receiver status that pertain to the antenna (see Table: Receiver Status). These bits indicate whether the antenna is powered and whether it is open circuited or short circuited.

If a short circuit or other problem causes an overload of the current supplied to the antenna, the receiver hardware shuts down the power supplied to the antenna. To restore power, power cycle the receiver. The Receiver Status word, available in the RXSTATUS log, provides more information about the cause of the problem.
