1. Converting a fixed phone to a remote antenna fixed
phone
This document tells you how to convert a QUALCOMM Globalstar GSP-
2800/2900 Fixed Satellite Phone to a Remote Antenna Fixed Phone (RAFP). Two
conversion options are available: the fixed phone quadrifilar helix antenna
remotely located or the module dielectric resonator antenna remotely located. To
use either of these options, you need to convert the Fixed Phone Radio Antenna
Unit (RAU). If you intend to use the Fixed Phone quadrifilar helix antenna, you
will need to modify this antenna as well.
Before you start you will need a kit that contains the following parts:
• RAU Brass Plug with Antenna Cables
• Module ODU or Bracket, Nut, and Washer
• New labels, as required
2. Converting the fixed phone Radio Antenna Unit (RAU)
2.1 Modifying the Fixed Phone Radio Antenna Unit (RAU)

Caution
Ensure that proper electrostatic discharge (ESD) equipment is used
to avoid damage to circuit cards, modules, and other electronic
components.
1. Remove the access cover from the RAU by unscrewing the captive
thumbscrews on the front of the access cover at the top and bottom.
