Just as a way-out idea: How about a large ferrite rod on the end of a
walking staff, on top of a backpack, or hidden inside a top-hat?

A small remotely tuned loop (say 12” diameter) would seem to be the best choice, as it would fit entirely inside a small backpack. It could have  modest efficiency while not requiring a counterpoise wire. Rigid 1” copper pipe formed in a square would be convenient to deploy.
