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.
