Stainless Steel Super heavy duty antenna stud. 3/8-24 , So-239 input for cable. Made with superior materials and is best mounted to a strong surface.

The plastic washer/insulator is oversized to help spread out weight, but protruding portion of it that is supposed to stick into the hole in your mount is still 3/8", so you don't have to buy any special brackets or drill a larger hole for this to fit.
