                                                              The BMA series of Omnidirectional antennas are co-linear
                                                              arrays of designed to transmit and receive applications
                                                              where 360° azimuth coverage is required. The antennas
                                                              are housed in self-contained fiberglass radomes and mount
                                                              vertically in portable man pack systems, on fixed and rotary
                                                              wing aircraft, and at various tower locations.

                                                              The low profile BMA-2-0 is commonly used as a camera
                                                              mounted transmit antenna in large crowd applications
          Key Features                                        and covert installations. The BMA-6-0 is used on airborne
          ► Light Weight                                      and ground based vehicles for both transmit and relay
          ► Easy Mounting                                     applications. The BMA-9-0, BMA-11-0 and BMA-14-0
          ► Weather Resistant                                 omnis are ideal receive antennas for smaller markets
          ► 360° Coverage                                     where steerable antennas are not feasible.
          ► Aerodynamic
          ► Low Profile                                       The antennas are linear polarized and will accommodate up
          ► 1.4 to 15 GHz Available                           to 60 watts of power. VSWR is 1.5:1 and input connection
          ► 2 to 14 dBi Gain Available                        via type “N”, SMA, or waveguide flange. Mounting brackets
                                                              and aerodynamic radomes are optionally available.

Description: Omnidirectional antenna, that is, the performance graph in the horizontal direction is 360 � are uniform radiation, which is usually referred to no direction, the performance graph in the vertical direction to a certain width of the beam, in general, the smaller the beam width, Gain greater. Omnidirectional antenna in mobile communication systems and the general application of the system of suburban stations Region-based, large coverage area.
