The Antenna Unit (AU)

The antenna unit is composed of the antenna element array, necessary high power and low noise amplifier systems and a tracking system.

Two AU versions exist: a 2-axis unit intended for land-mobile and fixed-site installations and a 3-axis unit for the maritime environment.

Connection to both AUs is made by a TNC connector. The single co-axial cable carries RX, TX, power and tracking information.

Installing the Antenna

WARNING: Avoid exposure to microwave radiation. Keep a safe distance of minimum one 1 meter (39 inches) to the side and above the antenna. Always power the MSAT-G2 down prior to disconnecting or connecting the antenna.

The antenna port is a 50 Ohm female TNC. This line carries RF, signaling, and DC power for the antenna. Note: Grounding the center conductor while power is applied to the transceiver can cause the transceiver's fuse and/or a fuse in the vehicle to blow. No modifications should be made to the RF cable under any circumstance.

Keep a clear line-of-sight to the satellite. Preferably, avoid all obstructions within three (3) meters of the antenna. Obstructions less than 15 cm (6 inches) in diameter can be ignored beyond this distance.

If the antenna is being mounted on a vehicle it is important to ensure there is a clear line-of- site to the satellite(s) in all directions. After the radio is commissioned and operational it is recommended that the signal strength be checked while the vehicle is slowly driven in a 360º circle. The signal strength should not vary significantly or be degraded in any particular direction.
