The Larsen RGNMOSS Gasket for NMO Coil creates a water tight seal beneath the NMO coil when it's tightened onto the NMO mount. The RGNMOSS gasket is necessary to prevent water from leaking through the NMO mounting hole, and inside the coil.

Keep your Larsen NMO antenna watertight with this genuine Larsen part.
