[ADXA] Receive antenna question

[Dennis Schaefer]

Great answers to my question about second transmitter in-band operation!

Here’s another FD-related question.

This year, our club set up in a recreational area owned by a local
industry.  This was perfect except that noise was a problem.  We assumed it
was from the two processing plants, which were less than a half mile to the
south.  We need to do some mobile ops to see where the noise is coming
from, but the plants are the main suspects.

We don’t work many stations from the south, so a directional receive
antenna that would favor N to E would be great.  There is info on low-band
receive antennas, but none on how they would work on higher bands.

My pennant antenna suppressed noise well on 160 and 80 but I never thought
about trying it on higher bands.  It is packed away now, for summer.

Would an antenna like a pennant, flag, K9AY loop, BOG, etc, work to
suppress noise from the South and give a better S/N in favored directions
on 40M and up?   Would it be possible to scale them smaller for the higher
frequencies?
