Vehicle Installation

NOTE: Each antenna has specific installation instructions. Please refer to the antenna installation instructions for specific requirements and details.

Mount GPS Antenna (optional)

The iR1200 GPS-Enabled modem comes equipped with a connector for a GPS antenna. Nextel has tested and recommends using the GPS Magnetic Mount Antenna (part number 5030-C5-RFM) with the iR1200 Modem.

The following table contains the steps for mounting a GPS antenna.

1Use an antenna suitable for the GPS of frequency 1575 MHz with an MCX connector and matched for 50-ohm impedance. (Use only an approved antenna – see list of Approved Antennas on page 22.)

2Position the antenna where it has a direct line-of-sight to the satellite.

3Mount the antenna according to the manufacturer’s specifications or instructions.

NOTE: Because of the operating frequencies involved with the GPS signal, splicing or using adapters to extend the length of the antenna coaxial cable is not recommended and will likely prevent the system from operating properly. We recommend that a single length of coax without splices or adapters be used.
