The signal bars are low or fluctuating and the call quality is poor on my Inmarsat Service.

Ensure that the following are observed:

• All antenna connectors are hand tight. Not too tight as it will break the connection.
• The antenna is installed in a location that has a direct line of sight to the satellite and there are no obstructions.
• BEAM certified antenna cabling is being used and there are no sharp bends or cuts in the cable, and the cable has not been modified in anyway
• If using a fixed passive antenna, ensure it is orientated correctly and pointing at the correct satellite.
