A round balloon can be made to 'function' in a similar manner by
placing a [cardboard or plastic] disk of sufficient size beneath the
balloon. This will act to give lift to the balloon, maintaining it
near vertical from the ground.
The larger the balloon, the larger the disk required.
Been there, done that ... worked LZ1KDP years ago during a Winter
windstorm with 100 watts.
