New Kathrein UF antenna panels for circular/elliptical and slant polarisation The Kathrein Broadcast Division has extended the product range of UF antenna panels to new types of circular/elliptical and slant polarisation. During the development, special attention was paid to making Series 75122 orizontal and vertical dipole system in one antenna housing. Separate inputs for and V provide flexible external cabling. All types of elliptical and linear polarisation can be realised by appropriate feeding by external power dividers and phase cables. Building block for antenna systems with excellent omni-directional radiation patterns and VSWR in the range 47 654 Mz. In special configurations they can be used in antenna systems up to 694 Mz. sure that constantly good omni-directional patterns could be achieved for the polarisation planes in the entire specified frequency range. Series 75125 orizontal and vertical dipole system in one antenna housing. A single input and integrated power splitter enable compact design of antenna systems with simple distribution network. Internally set power division for elliptical polarisation with a power ratio of 7% and % V.
