It appears from his OP that he was able to get a rope over the branch last time, so it

If it doesn't go well he can use a sling-shot and some fishing line, or
string. Ham radio guys have high quality sling shots with attached

use that to pull up a radio antenna. But for less frequent use, one
should be able to make one.
