LAIRD's NMOHPCG518 permanent NMO mount provides extended frequency range up 6 GHz. This allows antennas in frequency ranges above traditional LMR195 equivalent frequencies to be deployed. 78 rockwell hardness brass material resists corrosion, gold-plated contact provides superior conductivity and available coax options are: LMR195 equivalent, 17 ft RG58A/U or 17 ft RG58U.
