[amsat-bb] Antennas

[Joe Fitzgerald]

Tom,

You are correct in that the antenna with the smaller effective aparature
will collect less energy in a given time period.

But things are never equal - preamp performance, feedline loss etc.  For
satellite antennas, maximizing Gain/Noise Temperature is essential figure
of merit.   It does little good to collect lots of energy if that energy
is thermal radiation frin the roof under your antenna!
