[Elecraft] low-noise 40m RX antenna?

[Wayne Burdick]

I recently had to erect a temporary random-wire antenna, thanks to the
less-than-skilled tree trimming that brought down my real one. The
stand-in is shorter and much closer to noise sources on my property. The
result is 1 to 2 more S-units of noise on 40 meters and some other bands.

Since the K2 has a separate RX antenna jack (on the K160RX module), I'm
thinking about putting up a low-noise receiving antenna for the low
bands. Unfortunately, to get enough wire for a Beverage antenna, I'd
have to sneak something along the fences in the power company easement
behind my house. This leads me to wonder about other possible low-noise
antenna solutions that might take less room (tuned loops, etc.). 40
meters is the band I'm most interested in.

Any suggestions? I think this topic might be of general interest for
weak-signal DX and QRP work on 40, but you seldom hear any discussion
about low-noise antennas outside of their application to 160 meters.

tnx
