[Elecraft] low-noise 40m RX antenna?

[Stuart Rohre]

The greatest low noise and gain antenna is a horizontal loop, if you have
the room for a wave length of wire.  It has both low and high angles of take
off.  If you use a transmatch, you could put up less than a wavelength at
80m and just feed it with parallel line, and a transmatch.

Verticals can be a noisy antenna if mounted too near the ground.  Most urban
noise is vertically polarized.  Vertical dipoles are best, vs. quarter wave
radial ground verticals.
