I would argue, as well, thatit is fallacious (as K2UVG did) to count double
for antenna dB, on the theory that they help both transmit and receive --
my own belief is that below 6 meters, and maybe there as well,
environmental noise is the limiting factor, not system gain. Hence the
value of directive antennas on all bands, to improve the overall S/N ratio.
As Tom says, the tradeoffs are mighty complex, and every time you change
the baseline by making one improvement or another, they need to be redone.
