How does rain (rain fade) impact your services?

Rain fade is all about signal absorption and scattering of incoming signal. By far the greatest single event reduction (not elimination) in power of signal is caused by rain, not so much water vapor, i.e. humidity and fog.  Since rain only forms in the troposphere, which extends seven miles above the earth, and satellites in geostationary orbit are 35,800 km (22,500 miles) above the earth, a signal travelling through a rain cell will experience attenuation during only a very small portion of its transmission path. In fact, terrestrial microwave transmissions (always in the rain) are more susceptible to the effects of rain attenuation because their signal paths are entirely in the troposphere, and the signal may pass through an entire rain cell.

Squire Tech’s network is designed around ‘powering through’ (i.e having enough BUC power and up-link power at our teleports) to transmit through heavy rainfall. Our Ku frequency iDirect satellite networks are built to dynamically increase in power as long as you are using a stable .85 meter or greater AvL satellite antenna which has lowest in industry backlash impact from wind and rain.

Note: Although we do support all greater size aperture dishes, we do not see great economic/performance value in 1.2 meter Ku Band antenna upgrades over 1.0 meter for purposes of weather performance.
