| These springs are made of stainless steel for many years of service. Two basic models (ring terminal connections and screw-on connection), each available in a medium duty model and in a heavy duty model, are available. Each spring stands about 3 inches (77mm) above the mount surface.
The medium duty models are great for 2 ft heavy
fiberglass antennas as well as 3ft light duty fiberglass antennas.
The screw-on connector models (SS-34AM & SS-34AH) utilize our premium SO-239 base design. The strength and performance of this design has made it the standard by which all other similar designs are judged by. As expected, the hardware on these models is stainless steel and all insulators are molded in nylon.
