Calling N8KDV
 

If I shot a wire up over the highest limb of the fir tree in my yard, and
connected the ends to make a loop out of it and ran the lead from the loop
to the house via the insulator in the tree trunk, would that be a good SW
listening antenna - would it have any directionality (just one loop but
100' or so long) ? THANKS

You gonna feed it with coax or just a single wire? Give it a try at any rate
and see how it works.

Probably work OK..
Be a great Lightning rod too ...

MAXIMUS,

Sounds like you would have the Wire Antenna Element going from
the Insulator up the Tree to the Limb and back down the Tree to
the Insulator. Then from the Insulator via the Feed-in-Line to
the Radio in the House. Yes you have a Loop but it is so
narrow and thin that it effectively a Vertical Antenna and thus
basically an Omni-Directional Antenna. You could use 300 Ohm
Twin Lead or Coax Cable with a Balun; plus a Ground Rod and
Wire at the base of the Tree.

NOTE: Using a 'thin' 'narrow' Vertical Loop Antenna like this
can help reduce the Man Made Noise that a vertical antenna is
more susceptible to picking up.

The basic Antenna design used for this Field Antenna can be
adapted to many individual situations including your Vertical
"Up-and-Down" the Tree Loop Antenna.
