[Communications Link Problem ]During design of your satellite
you discover a readily available antenna that weighs the same as in
the original design but has a diameter twice as large. Assuming
this size increase is NOT a problem how much can you reduce the
transmitter output power from the original design of 50 watts
assuming the same data rate, bit error rate, and link margin?
