Profile: Flann Microwave Ltd. specializes in the design & manufacture of precision waveguide components, microwave components, antennas and assemblies. Omni directional antenna has been specifically designed to provide a vertically polarised 360° field of view with the widest possible acceptance angle in elevation. This allows the tracking of sources above and below the horizontal plane or alternatively maintain mobile communication between nodes over rough terrain. The antenna is suitable for many applications requiring good all round coverage. Our 063 series of instruments facilitates the continuous control of phase change over the range 0 to 360 degrees. These instruments are fitted with a low VSWR dielectric element coupled to a precision micrometer drive. The micrometer indicates the relative position of the dielectric element in the waveguide.
