Tom, why not use a pully and weight at one end of your wire
antenna? The pully would be fastened to one of the trees,
then the antenna rope through the pully and down to a weight.
Use a marine quality pully and dacron rope and the system
will last for years.
There won't be any advantage of using the aluminum wire except
lower cost.
