Provident Antenna
Satellite search
Before mounting the WorldPhone Provident antenna, look up the
relative position of the satellite,
see coverage map in appendix H –
System description.
The antenna must be pointed at the satellite with free line of sight for
optimum receiving and transmitting conditions. The beam is perpen-
dicular to the antenna.
When during adjustment of the antenna a satellite signal is received,
a short tone will sound. If it is an Inmarsat satellite, a continuous tone
will sound with varying frequency. When closing in on a satellite,
turning the antenna horizontally and adjusting its vertical angle, the
tone should increase in frequency.
See setup procedure for WorldPhone Portable in chapter 1. Getting
Started.
