7.78 Db BETTER [+1 1/4 S unit] than 100 watts.

Upgrade the vertical to a beam and the net gain can be as high as +19.78
dB [3+ S units] on the path:
1] + 6 dB in receive
2] + 6 dB in transmit
3] + 7.78 dB for the amplifier.

For $1400, a beam has a much better return on investment than an
amplifier by itself.

The #1 rule I teach new or aspiring hams is "Your station efficiency,
and your enjoyment, is directly proportional to your antenna."


RM I will agree that it is best to go with a beter antenna, sometimes it
RM is just not practical. Not many can put up a beam for 80 meters and
RM not that many for ever 40 meters. Most amps will do 80 to 15 meters.


Just wondering if it wouldn't be possible to compensate for antenna
size, by actively driving the reflective, directive elements using
correctly phased amounts of power from the xmtr output. I'm probably
preaching heresy in the midst of this bunch of laurelled gurus but I
don't mind being told I'm thinking laterally, so shoot your best
flames.
