Loss Of Signal / Rain Fade; Installation Using Long Cable - SELFSAT H21D2+ User Manual

Loss of Signal / Rain Fade

The satellite signal may be lost temporarily due to 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 antenna may reduce the satellite signal strength, snow should be
●
swept away as sppn as possible.
Tree foliage growth into antenna's line-of-sight to the satellite may result in gradual loss of picture.

Installation Using Long Cable

For installations where the RG 6 cable runs from the receuver(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.
