Bad weather can affect signal reception on even a well-wired, directional satellite system. Heavy rain can cause the signal to sputter in and out, frustrating satellite TV subscribers. If you live in a region of the country that gets a lot of rain each year, you’ve probably had this problem a few times. Snow and ice that build up on a dish can also affect reception, as can high winds.

During a rain shower, raindrops can weaken or absorb the signal on its way to a satellite dish. Rain can also cause signal scattering, as electromagnetic waves break and diffract around raindrops on the surface of the dish.

Mini dishes are better designed to minimize signal loss due to weather conditions. However, large dishes are better suited for areas where it rains a lot, because they compensate better for the loss of signal strength due to weather conditions.

Rain isn't the only culprit, though. Snow, ice, strong winds and dense fog can all affect the satellite signal.
