Bill:
I used flat, black rubber bungee cords to anchor two corners of my
now-removed horizontal loop and for the pulley and far end of my present
inverted L. The far end (non-feed point) of the L is terminated in an
insulator. The hook on one end of the bungee cord is looped through the
insulator (I had to open the wire hook a little). The other end of the
bungee is connected to the anchor rope; the rope terminates at the top of a
tree. This arrangement gives the horizontal portion of the L a little bit
of springiness when the anchor tree sways.
To support the pulley (or the corner insulators of the loop), I wrapped
the bungee cord around the tree trunk and hooked the wire hook back over the
cord itself. I squeezed the hook closed with pliers to provide a bit more
security. I attached the pulley to the other end of the bungee cord, as I
did with the end insulator, above.
The loop was in the air 9 years. I had to restring it twice when the
original dacron cord supporting it was cut by tree branches or by too much
tree swaying. But after I replaced two corner ropes with the bungees, the
thing lasted until I removed it last year. And the Inverted L has been up
in the air with bungee cord anchors for four years now, with nary a trouble.
You can find all this stuff (bungees and pulleys) at Home Despot. (I
know - the pulley's not marine material but it was there in front of me.)
