Does Weather have an effect on DISH TV?

How DISH Network Works

DISH Network uses a fleet of satellites in fixed orbit; that's, the satellites orbit the world at constant rate because the Earth's rotation, that the satellite appears to "stand still" over a selected space on the Earth's surface. These satellites ar clad in order that most areas of North America can have one in every of them overhead. The satellites beam programming all the way down to alittle, mounted dish put in at the customer's web site. DISH Network's satellites broadcast microwave frequencies in what's referred to as the element band, that is usually used for direct-broadcast transmissions.

Kinds of Weather that may have an effect on Reception

One feature of Ku-band microwaves is that they're additional simply scattered and absorbed by water droplets than the longer C-band waves employed by previous big-dish systems. As a result, heavy rain, dense snow, or thick overcast will cut the strength of the satellite signal by the time it reaches the customer's dish. whereas this sometimes produces issues solely throughout the peak of a storm, build-up of snow or ice on the dish will manufacture longer-lasting reception issues.

Symptoms of Weather-Related Interference

The interference to direct-broadcast satellite signals caused by weather is thought as "rain fade." it's sometimes practised as Intermittent loss of signal, poor image quality, pictures that freeze or become pixelated, and screen blackouts. Rain fade are often distinguished from alternative forms of reception issues as a result of it happens solely momentarily and affects all the receivers hooked up to the dish.

Solar Interference

While not weather-related, another heavenly kind of signal interference is that the sun itself. twice throughout the year, sometimes in early spring and time of year, the sun passes directly behind the DISH Network satellite for many minutes. throughout this era, the radiation placing the dish overwhelms the microwave signal. As a result, the house system can't receive TV signals. The precise temporal arrangement of those blackouts depends on the angle between the dish and also the satellite, and also the specific satellite the dish is aimed toward.
