A1585 (3.5 dB 800/900 MHz)

3.5 dB 800/900 MHz NMO Antenna


The A1585 is a heavy-duty 3.5 dB NMO mobile antenna with tuned 806–960 MHz options and an enclosed phasing coil.

  • Provides 3.5 dB gain for selected 800/900 MHz mobile bands.
  • Protects the phasing section inside an enclosed silver-plated coil.
  • Uses a 0.125-inch stainless-steel whip for heavy-duty service.
  • Offers brite or black versions across four frequency choices.

Customization: Cable type, cable length, and connectors can be configured for specific installation requirements.

Product Description

The A1585 is intended for 800/900 MHz mobile systems that prioritize gain and a heavier whip construction. Four tuned frequency choices cover 806–866, 824–896, 896–960, and 900–930 MHz rather than treating the entire range as one broadband configuration.

Its 5/8-over-1/2-wave design uses an enclosed silver-plated phasing coil and a 0.125-inch stainless-steel radiator. Brite and black finishes share the same 18-inch NMO-mounted form.

Ideal applications: heavy-duty vehicle LMR installations requiring a tuned 800/900 MHz gain antenna.

Example Model Configurations: A1585A-06, A1585A-24, A1585A-76, A1585A-87, A1585A-915, A1585A-96, A1585B-06, A1585B-24, A1585B-76, A1585B-87, A1585B-915, A1585B-96
