Review on 📡 Comet Original CA-2X4SR(NMO) Dual Band VHF/UHF Mobile Antenna with Fold-Over Hinge - NMO Connector - 140-160/435-465 MHz by Ben Hamilton

Every other NMO antenna I've ever bought had a rubber grommet that went between the base of the antenna and the area around the NMO mount. These gaskets were used to keep water out and to protect the painted area around the NMO mount. This antenna does not have this type of seal. It has a small rubber grommet (similar to a water hose) that fits between the threaded portion of the NMO mount and the antenna. While this can isolate the NMO mount from the antenna, it does not protect against water or the car's paintwork.
