Called 'em gin poles for the last 40 years or so. Never heard 'em called 
anything else. Not changing now!

Use a gin pole system here, like Tom G3OLB described, to support one end 
of my 160m dipole at 40ft, and the apex of my 80m Delta Loop at 64ft. 
Three sets of 4 guys. Raise it lower it on my own.

Some winters it falls over usually because one of the Barenco couplers 
have snapped again, again etc. Other times like this winter it stays up!
