Confidential and Proprietary Information
Line of Sight (LOS) Interruption
The SR1500 antenna needs a clear line of sight (LOS), or view to the satellite for
uninterrupted reception. Objects such as buildings, mountains, bridges, tunnels and
trees that block this view will cause a loss of signal. The signal will, however, be
quickly restored once the antenna has a clear LOS again.
Heavy rain, snow or ice may also interfere with the signal reception. Stray signals
from radio or television broadcast towers may also affect the satellite signal.

Standing Water Interference
When a vehicle is parked, rain and morning dew may collect on the radome of the
antenna. This may cause interference with satellite reception. Once the vehicle is in
motion, any standing water on the antenna should roll off and the interference
resolved. Clean the radome with a soft, clean cloth if necessary. Some aftermarket
water repellents are also available to help reduce rain and dew from building up on
the antenna.
Set Top Box (STB) Compatibility
Some STBs are more sensitive than others and may cause a degradation in
performance during marginal conditions, such as heavy rain, heavy snow, and
partially blocked LOS. The STB model should be selected, and an initial setup run, in
coordination with Gilat Technical Support to assure compatibility with the particular
application.
