Pulley Arrangement For Horiz. Antenna ?

Hi,
Pretty sure I'll probably be able to come up with something that will more
or less work, but was wondering if any of you folks have a real clever
solution for this:
Will be stringing a horiz wire listening only antenna between two trees
out back.
Trees have a fair amount of movement, particularly in the winter.
So, I thought I'd fasten one end securely, and then use the pulley
arrangement, with a hanging weight, like you see in all the pix for this
sort of thing.
But, we get a lot of ice and freezing rain, and I doubt that the pulley
would really function well, if at all in the winter.
But, perhaps ?
Think a large metal ring, with a Dacron rope goint thru (one end to the
wire end) would be better ?
Coat Dacron with Silicone Spray ?
Or,... ?

Bob,
Pulley's and jugs of anti-freeze have worked well for me through 5 winters
here in NH.
No apparent problems with "boat pulleys" seizing up. I would worry more
about friction on the
rope!. My 220 foot antenna of #10 copperweld with W7FG ladderline requires 5
gallon jugs of
anti-freeze and is supported with the double braided Dacron in about a 300
foot span.
