What's the "typical" tension necessary to keep a 88ft doublet aloft?
I'll also be supporting the midpoint where the feedline attaches.
Insulated 18awg will be used as the antenna wire.

This isn't very scientific, but I just pull the wire tight until most
of the sag is gone. Never had one break. Also, if using trees for
support, a screen door spring at each end, between the tree and the
insulator, will keep the swaying tree from snapping the doublet.

I tried all that scientific formula stuff, and the KISS stuff. But neither
made the tree rats happy.

So my answer is; put it up until the squirels find the line and chew it in
half, then put it back up.

I remember reading somewhere about a cure for the squirrels. I believe it
was a mixture of cayenne pepper and molasses on the support ropes. I had a
cat once that snapped food out of your hand like a dog. Fed him a jalapeño
one day. Cured him.
