OT: Receive noise / ground - NO NOISE

Ken G Kopp
The golf course that's adjoins my property lies between me and Japan.

Several years ago, in preparation for a 160M contest, I took one end of
a 5,000 foot spool of #22 telephone frame wire and tied it to a post in the
yard.  I then walked across the snow in the direction of Japan until I came
to the end of the spool, leaving 5000 feet of wire behind me in a straight
line atop the snow.  Worked well as a receiving antenna, but I -did- reel
it in during the day to avoid the snowmobiles. (:-)

73!

Thin wires do wonders.

A while ago the 160m SSB contest fell when I was at a conference on a 300 ft "mountain" in FL. Two #30 wires were strung from a window of a house on to 25ft trees 150ft away.  K2/AT matched it well and some 10 QSOs were made in 1 hr.

Modified Beverage antenna ?

Pretty much yes.  It would essentially be an unterminated
beverage-on-ground (BOG), which is bidirectional. They work surprisingly
well, and you don't need 5,000 feet of wire to do it. In the past I've
laid out 500 feet and had surprisingly good results, although generally
speaking something closer to 750 is considered good for 160m.  The gain
might be a bit less than an elevated (i.e., 6 to 8 feet above ground)
beverage and the characteristic impedance will be a bit less (closer to
300 ohms than 500 if you decide to terminate the far end to ground to
make it unidirectional), but a BOG is hard to beat for a simple receive
antenna.  Aside from the possible benefits of polarization,
directionality is what makes a good receive antenna and a BOG has that.
