Topband: making a bev seem longer

[chacuff]

I don't have problems with noise...which may be why RX antennas don't perform a whole lot better than my TX antenna. I wouldn't say it's extremely quiet but it's not excessively noisy.  Hope to play more with antennas this fall and winter.

A loop such as that has a very narrow null at very low angles, and
therefore it's usually not very effective for anything except for local RFI
or another local ham. For power line or nearby QRN, it's useful. But that's
about it. There are much better RX antennas.
