Loss of Signal/Rain
Fade
~
.The satellite signal may be lost temporarily due to
£=:~=:7
unusually heavy rainfall. An optimally aligned antenna,
"'"
along with the shortest possible cable run, minimizes
"
the chances of "rain fade."
.Make sure the antenna is mounted securely to prevent it
from being blown out of alignment in a heavy wind.
.Heavy snow accumulation on the LNB and the antenna may
[fI]
~
reduce the satellite signal strength; snow should be swept
--away
as soon as possible.
-~-
.Tree foliage growth into antenna's line-of-sight to the
satellite may result in gradual loss of picture.
Installation
with Long Cable Run
.For installations where the RG 6 cable runs from the
receiver(s) to the LNB far exceeds 100 feet (150 feet or
more), as encountered in a commercial or multi-dwelling
building, you need to use an AC power booster module to
/
bias the LNB.
/
.You will also need an additional RF signal amplifier to
compensate the signal amplitude loss. Otherwise, your
antenna and receiver may not work properly and be subject
to frequent outages in adverse weather. Contact a
professional concerning such installations.
