I once threw a weight with a transformer wire and some string attached to it over a high tree branch in my yard to see if it would make a decent antenna for my SDR, it worked!
It was an extremely inexpensive ~5m antenna
My Lawyer says not to tell you a spud gun can heave a line a good height/distance if you want to make a folded dipole antenna using an old growth fir tree.
Just tie your line through a hole in a soup can and put it over the muzzle before firing a spud.
