Weather impact on Satellite Signal

by B.W. Cosman P. Eng
(Rothesay, N.B. Canada)

Your very useful and instructive article on comparison of Cable vs Satellite failed to discuss the problem of occasional service interruptions caused by serious signal attenuation due to thunderstorms and Snowstorms.

This becomes more severe in the more northerly latitudes as the antennae has to be pointed lower to the horizon.

The quality of the receiving system (sensitivity etc.) will generally not overcome this limitation. Often the effect will be more evident on signals from one satellite to the other depending on the alignment of the particular antennae.

This factor would favor Cable or any other TV service carried over ground based facilities such as TV over telephone lines or fiber optics.

TV service over telephone lines and/or fiber optics is currently being provided in several cities of the Atlantic provinces of Eastern Canada. (New Brunswick and Nova Scotia)
