[Elecraft] Recieve antennas in an Urban area

[Robert Tellefsen]

Good morning Rich
I have three receiving loops here--a full size Flag loop pointed toward
New York, a tuned 160m loop and an untuned coax loop for 80-40-30m
The last two loops take turns sitting on my portable base with a small
Radio Shack TV rotator.  During contests I put it in my front yard,
well away from my transmit antennas.  The rest of the time, these
two loops are taken off the base and leaned against my fence inside
my back yard.  Because of their relatively small pickup area, I use
an old Ameco tunable preamp with them.

The full-size Flag loop is suspended between two masts that also hold up
various other antennas.  Its main claim to fame is a cardioid pattern
that gives it a good rejection off the rear.  Since that is where a lot of
my local suburban noise comes from, this is a relatively quiet antenna
for me.  Its primary use is on 160m, but it also works FB on 80, and
even 40 at times.

There is an excellent site for the Flag loop with all kinds of good info at
http://www.angelfire.com/md/k3ky/page37.html

For the rotatable loops, there is also a ton of material on the web.  Just
search for "loop antenna" and you'll find enough reading tokeep you
busy for a while :-)

Good luck and 73
