I agree with Tom, and two practical examples come to mind. First the
Pennant, which has a stated gain of MINUS 30 dBi, and the shielded loop
(SLOOP) which is also a loser gain wise. Fact is the noise control yields
s/n levels that make a station readable, when on say the transmit vertical,
he is not. We find similar needs for low s/n ratios on moonbounce (EME), and
are always striving to achieve a lower noise figure amplifier, along with
the highest gain antennas we can manage.
Happy Building, Geo KØFF
