This is a printed ground stake for the POTA 20. Simply unscrew the bottom cap and screw this in. The spike is permanently secured to the threaded insert. This will provide enough support for the Carbon 6 to remain in the vertical position when used with a light gate 26awg wire antenna. Additional guying can be used if more support is needed for a feedline or heavier antenna. The spike is printed in ASA to ensure strength and UV protection even in warm environments.
