Tom,
I don't think any one who designs a system "wants" this to occur, but as a
function of overall system cost it is one of the unavoidable realities.
Its actually a great compromise, because with only a 3db loss you can use a
linear rec. antenna with no polarity switching, and avoid the large fading that
would occur if the satellite was transmitting linear.
Now if you have the money to build a satellite that can point itself at the
receiving station at all times ie: geo synchronous:)$$$$ then that would be the
cats meow;)
