Clear Line of Sight means that there is no blockage from VSAT terminal to satellite in the sky. This is typically in a North Westerly directly for the IS37 beam and East for the IS33 beam. Obstructions will result in a degraded signal, resulting in a poor, intermittent broadband service or no service at all. This means that one will need to monitor the growth of vegetation or construction of new buildings in order to prevent obstacles that can block this line of sight.
