Mounting of Provident
Antenna
Satellite search
Before mounting the WorldPhone Provident antenna, look up the
relative position of the satellite,
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.
Coax cable
A 10 metre coaxial cable type RG-223 (QRPM 911091-10000) is
supplied as standard.
A bracket is available with N-connector receptacle for connection of
extended antenna cable
Source of energy
The equipment operates from 10 to 32 Volts DC from any 12V or 24V
battery, using the 2 m DC power cable, QRPM 911080-2000. The
positive lead of the power cable is tagged.
