5.1) DOES WEATHER AFFECT RECEPTION?
The answer to this question depends on the type of system used.
For systems that transmit their programming without modification
(ie. No compression or scrambling), severe fog and/or rain can
cause the signal to be reflected, causeing the picture to
deteriorate. From what I have heard,you can usually expect
between eight to ten days per year of interrupted service. This
figure, I believe, is the average for the current systems
operating in the U.S..
If the programming is scrambled, the downconverter/descrambler may
loose authorization sooner.
On the other hand, if the programming is sent digitally, or is
digitally compressed, the signal can deteriorate to a much lower
level before the picture is affected. However, once the signal
gets this weak, the picture will deteriorate at a much faster rate
as the weather gets worse. From what I have read, the average
number of days that this type of service would be interrupted,
would be one day per year. (This sounds rather optimistic to me...
does anyone have any info about this?)
Also, the farther the receiver is from the transmitter, the sooner
the picture will be affected.
