I'm really surprised to keep seeing that comment these days, when
everyone should by now know that antennas are more or less reciprocal
for transmit and receive. The average ham on the other end is most
likely running similar rigs and similar power to your 150 watts, and
that means that signals should be roughly the same either way no matter
how good or how bad your antenna is. If you're using a good antenna
that hears well you are almost certainly putting out a decent signal
with it. If you're using a poor antenna that doesn't transmit well, it
just means you aren't hearing a lot of stations you'd be able to work if
you had a better antenna.
This stuff is pretty basic ....
Yeah, but there's an elephant in the room that you're leaving out of
your analysis -- it's the RF noise that surrounds virtually all of us,
both from trash generators in our own homes and those of our neighbors!
Any ham who hasn't gone through the work to purge at least his/her own
home of those noise sources is RF deaf! And even after finishing that
task, is likely still deafened by neighbors' trash.
Indeed, the principal benefit of directional antennas and serious
chokes at antenna feedpoints is to reject as much of that noise as possible!
