Ground Strap Kit for Antenna, Radio, and Intercom Systems combines an NMO ground cable and a radio/intercom grounding cable. This kit improves performance and distance of your two-way radio, antenna, and intercom system. The NMO Ground Cable mounts to the antenna's brass fitting and to your roll cage, enhancing performance for antennas not on metal roofs. This kit is compatible with 3/8in NMO Cable only and now features black wiring. The grounding cable mounts to your existing intercom, RM60 radio, and to a bare metal surface, reducing RF interference within your system. This is particularly valuable for powder-coated frames. The cable length totals 42in, with 30in from intercom to chassis ground.
