Antenna Mount for Stand Up Paddleboard

This is designed to hold a telescopic whip antenna to your paddleboard using a bungee cord. You're going to need one of those red threaded antenna branches designed for dipoles, and a 10m screw to attach your ground wire, and drape it into the water. The antenna goes in the hole pointing at the sky. 

The bungee cord attaches to the board wherever you can, pulled tight, and either tied off or clamped off, and this will hold the contraption to the deck of the board.
