Mast Support for Portable Antennas for Field Day and POTA and Emergencies.

We show an easy to make support for telescoping mast antennas for radio amateurs. This can be quickly set up by one person and does not require guy lines. The support structure can be used as the counterpoise for an end fed antenna (EFHW). This allows fast and easy set up of antennas for emergencies, for field day, and parks on the air (POTA).
