Introduction
Satellite Television
Satellite television uses satellites in a stationary orbit over the Earth to 
deliver television and audio programming. This type of orbit enables the 
satellites to stay aligned over one place on the surface of the Earth. Once the 
satellite dish is aimed at the satellite, the dish does not have to move.
Satellite Signal Quality
Rain and Snow Fade
Heavy rain, snow, or cloud cover can block the satellite signal, which can 
interrupt your programming service. By aiming the satellite dish to get the 
strongest signal during installation, you can help prevent rain and snow 
from interrupting the signal. Your service will return after the weather 
condition has passed.
Solar Interference
Twice a year, the sun moves to a position behind the DISH Network satellite 
as it orbits the Earth. The exact time of the year that this occurs varies, 
depending on the location, but it is near the beginning of spring and again 
near the beginning of autumn. The period of solar interference lasts for a 
few minutes at about the same time everyday for a few days during the 
spring and autumn, so do not be alarmed when it happens.
This is an unavoidable natural event for all television involving the use of 
satellites and has an adverse effect on many program providers. During 
these brief periods, you will not be able to see programs on DISH Network. 
Once the sun has moved from behind the satellite, the programs will 
reappear.
Tip: If you lose 
your picture, it’s 
most likely due 
to heavy rain, 
snow, or the  
build-up of snow 
on your dish.
