In addition, since satellites are located 22,300 miles (35,900 km) above
the equator, the TracPhone antenna must have a clear view of the sky
to transmit and receive signals. Anything that stands between the
antenna and the satellite can block signals, resulting in lost data.
Common causes of blockage include the following:
• Trees, buildings, and bridges
• Other vessels docked alongside your vessel
• Onboard masts, antennas, or other structures
• Inclement weather conditions
