[Elecraft] Question about suspending a delta loop...

[Geoffrey Mackenzie-Kennedy]

Rick,

Thank you for your reply, and my apology for taking so long to acknowledge
it.

I did at first try using bungee cords in GM land as Gary VE1RGB uses them,
and for the reasons which Gary mentioned, but unfortunately the squirrels
(mostly red) living on the farm there liked  to chew bungee cords enough to
render them useless.  Thereafter I used UV resistant marine rope and Kevlar
to support my antennas, neither of which squirrels like to chew it seems,
together with "fused" counterweights.  For the elements of my 40m wire beams
and for my other antennas I used jacketed Flexweave, the jacketed type to
protect the wire from the claws of the birds who perched on the antennas.

If your antenna's wire can move through the supports which are not on your
property without being damaged, a "fused" counterweight hanging near ground
or a suitable bungee cord at the support on your property might be
sufficient.  Of course an antenna's support ropes should always pass through
pulleys and not over branches, unless the antenna is a temporary
installation.  Marine pulleys (6mm) as used in small sailing boats have
served me well.

Any rope passing over a branch to support a pulley should be "wiggled" every
eight or nine months to prevent the tree from growing over the rope, which
would make it difficult/ impossible to move the rope later on.

If you cannot find suitable bungee cord and are interested in knowing more
about the "fused" counterweights which I used, please let me know.

73,
