ClockWatch Star Sync GPS
External Antenna


Available from Beagle Software is the Gilsson  active antenna. This  antenna averages about 28 dB signal gain.  This remote patch antenna greatly amplifies GPS signal reception.
 
  • Amplified (active) GPS antenna for exceptional GPS signal reception.
  • Built-in magnets for mounting on car rooftops or other metallic surfaces (user-removable)
  • Built-in permanent mounting holes for mounting on building or vehicle surfaces.

Using other External Antennas with the Star Sync Receiver Other active antennas may be used with the External receiver if it conforms with the following requirements.

Gain: Antenna should provide between 10 dB to 30 dB net gain between the antenna feed point and the connection to the Star Sync receiver. Consider all amplifier gains;. filter losses, cable losses, etc. when calculating the gain.

Connection: MCX male connection. An antenna with a different type of connector can also be used.

Antennas with BNC, N, SMA connectors

Other types of antennas can also be used if:

  • a suitable adapter is used to connect to the MCX jack
  • the active electrical nature of the connection is observed
     

Other antennas terminated in a BNC, N or SMA connector may also be used if a  MCX  Adapter is used (available from Beagle Software). Place the MCX adapter between the connector on the end of the antenna cable and the connector on the Star Sync receiver.

The total noise on the external antenna must be <= 7dB with a gain between 10 dB and 40 dB. Properly bias the antenna from receiver source or an external source. The Star Sync receiver supplies 3.0 VDC to the center conductor of the MCX female relative to the connector shell ground. The source resistance of the DC supply to the center of the conductor is approximately 10 ohms, which is included as a current limiting resistance. This resistance allows the receiver to survive momentary shorting of the antenna port. There is no provision to protect against a continuously shorted antenna port.

If bias voltage is supplied from an external source than the supply must be 4.0 to 8.0 VDC bias through the series combination of an on-board ~10 ohm current limiting resistance and a Schottky diode.

In either case the antenna must not draw more than 60mA.
