SBX-3 Reference Manual
51
The MGW-1 requires a 50
Ω
impedance antenna
extension cable such as RG-58U (up to 10 m (33 ft) in length) for
proper operation.
Caution – Antennas threaded onto a mount should be tightened
only by hand. Over tightening may cause damage to the antenna.
Damage caused by over tightening is not covered under
warranty.
4.2.6 AVL-1
The AVL-1 is designed for installation inside of a vehicle.
The AVL-1 has three ports: an AM/FM antenna input port, an AM/FM
radio output port, and a beacon signal output port. The AVL-1 is
powered by the beacon receiver, using the voltage applied to the center
conductor of the coaxial cable.
To install the AVL-1:
•
Unplug the AM/FM antenna from the AM/FM radio within the vehicle
•
Plug the AM/FM antenna into the AVL-1 port labeled ‘AM/FM Antenna’
•
Plug the port labeled ‘AM/FM Radio’ into the AM/FM radio
•
Connect the SBX-3 Evaluation Module to the AVL-1 port labeled ‘Beacon
receiver’
•
Use tie-wrap, hook and loops, or a similar mechanism to mount the AVL-1
in a convenient location.
4.2.7 Routing and Securing the Antenna Cable
CSI Wireless antennas require a 50
Ω
impedance antenna extension
cable such as RG-58U for proper operation.
Beacon-only antennas may be interfaced to a receiver with up to 150 m
(492 ft) of RG-58U coaxial cable. Antennas incorporating a GPS
antenna (MGL-3 or MGW-1) may be interfaced to a beacon/GPS
receiver with up to 10 m (30 ft) of RG58 coaxial cable due to more
significant signal losses at the higher GPS frequency (1.575 GHz).
