jbow, i have seen some drones do some fairly intricate things, so wha tyou propose might work.  It just would not be very cost efficient now.  Where similar principals would be useful is precision work in places dangerous to humans like repairs and recovery in radiated zones like when the nuclear reactors in japan were compromised.

Tie a rock (or an adjustable wrench or anything like that) to the right size cord, swing it up there until you get it over the limb, lower it, tie a pulley to it, run your cable or a cable attached to an insulator to the cable, pull it back up to hang under the limb, wrap the original cord around the tree until you can tie it off. If you're running a long wire for medium wave, run the other end to your house. The pulley will keep the wire taut when the wind blows and keep it from snapping. If you're running anything else, same thing just maybe the connector to your set coupled to a different place. Oh, tie a gallon bottle filled with water (or a brick) to the line hanging from the pulley, doh!
I still have my old SWL 7 multi trap antenna from the '60s.
It doesn't have to be that high but it will be directional. They also made an SWV 7 vertical antenna but I don't know how good it was.
The pulley trick works great for keeping it taut and keeping it from snapping. I'd give it a couple of ft.
I have two Hallicrafters SX-43s too, one for parts. I use a couple of newer rceivers now but those old Hallicrafters were good radios.
They are general coverage but they cover everything from long wave-medium wave-short wave. I never got into HAM  radio but was heavy into SWL.

Thank you so much for your comments and insight.
 
I started off as an SWL. and yes, for receiving height isn't an issue as much, plus back in the day they sw bands were crowded with booming signals and the old radios had a nice front end.
 
Chunking the wrench/etc wont get me the height I need and I was a terrible baseball player in school physical ed/LOL
 
However I am erecting a transmitting/receiving antenna and the height above ground affects the Z plus angle of radiation, so I have to get at least 30 feet for the ends. I see there are some homebrew contraptions that consist of a slingshot plus a fishing reel to shoot the line over a limb. I may try to tinker with that

Green Acres is the place to be
