What you need are a set of climbing poles, which needs the poles, 3 ropes and
a weight. The climbing poles are very two long rods with a hook on the end
of each able to slide along each other (but not tilt !). The poles extend
via two ropes, one per pole attached to the base of that pole and to near
the top of the other. Then you hook the first pole over a branch. Pull on a
rope to extend the second pole and hook it over a higher branch. Continue
branch by branch up the tree. This contraption can carry a weight attached
to a third rope with a release mechanism (a breakable tie for example). When
over the branch you want, pull the rope from the correct side so the weight
comes over the branch and back down to ground. The climbing contraption also
needs to be tied to the rope so you can unhook it from the lower branch.
After this, curse the fact you forgot to tie the aerial to the rope and
start again.
Hard work. It is easier to fire up a weight in a catapult. To stop leaving
failed projectiles (e.g. tennis balls) in the tree, make the projectile out
of ice, it will then melt.
