Assuring quality of service
There are conditions that can compromise the Cabling
quality of the service you may receive. These include: Using an externally mounted antenna provides
• Obstructions an ideal solution for many applications. It is very
• Cabling important that both the antenna cabling and
• RF Interference antenna are BEAM approved products. Always
ensure all RF connectors are screwed together firmly
Obstructions
and ensure there are no sharp bends in the cabling
Nearby tall buildings or similar structures, between the Terra 800 and the antenna.
heavily leafed trees and mountains can all
degrade performance as they block the signal RF interference
between the antenna and the satellites. All wireless devices, including satellite
Inmarsat performance is immune from natural telephones, are susceptible to RF (radio
environments such as clouds, fog, rain, snow, frequency) interference from other electronic
wind and smoke. devices. This problem is more evident when
numerous antennas and broadcasting devices
are located within close proximity to each other.
Symptoms of RF interference
Symptoms of RF interference often resemble
those that arise when an antenna is being
operated with an obstructed view of the sky.
Some of these symptoms include; erratic or no
signal strength indication dropped calls or warbled
or otherwise distorted voice. These symptoms may
be intermittent or persistent, depending largely
on the interference source, its distance, strength
and frequency relative to the antenna.

Mitigation of RF interference
Service degradation due to RF interference can
be significantly improved by:
• Increasing the distance and moving the
antenna off axis from the source of the
interference, and
• Using an external band pass filter and an
external antenna.
WARNING
Failure to use BEAM approved antenna cables will
result in degraded performance and may damage
the Terra 800. This will void the product warranty.
