5 Digital TV Solutions I UHF Omnidirectional Antennas I 5 UHF Omnidirectional Antennas In order to achieve a satisfactory grade of coverage and taking into account the requirements for higher field strength, needed for mobile and indoor reception, gap filling antennas with low wind load are necessary, at least in urban areas or metropoles. Our super turnstile antenna family from 7W to 15 kw is giving the optimal answer to this request. Main features Plug and play Horizontally polarised Low wind load Low weight Broadband performance Excellent electrical values Fully assembled Steel adapters for tubular masts available Order No Input 7-16 female 1 5 / 8" EIA flange 1 / 8" EIA flange Max. power [W] Frequency range [MHz] VSWR Gain (at mid-band) [d] Radome diameter [mm] 2 52 Height [m] Weight [kg] Wind load (at 16 km/h) [N] ,2 4,5 Max. wind velocity [km/h] 24

7 Digital TV Solutions I UHF Antenna Panels for Circular/Elliptical and Slant Polarisation I 7 UHF Antenna Panels for Circular/ Elliptical and Slant Polarisation All Purpose Panel Series 75121, -211, -212, Broadband Omnidirectional diagrams for square masts 66mm Circular, Elliptical Antenna Series 751 and -1 The Kathrein Broadcast Division has extended the product range of UHF antenna panels to new types of circular/elliptical and slant polarisation. During the development, special attention was paid to the production. Separate inputs for H and V provide flexible external cabling. V 26 H 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 omnidirectional radiation patterns and VSWR in the range MHz. 1 64

8 8 I Digital TV Solutions I UHF Antenna Panels for Circular/Elliptical and Slant Polarisation Elliptical Antenna Series MHz 55 MHz 65 MHz Single input and integrated power splitter enable compact design of antenna systems with simple distribution network 7 / Internally set power division for elliptical polarisation with a power ratio of 7% H and % V 18 Building block for antenna systems with excellent omnidirectional radiation patterns and VSWR in the range MHz Slant Antenna Series MHz 55 MHz 65 MHz 75 MHz 15 inclined dipole systems built in an upright antenna housing allow compact design of antenna systems (panels need not be mounted twisted!) Slant polarisation with a polarisation ratio (field vector) 8% H and 2% V Component for antenna systems with good omnidirectional radiation patterns and VSWR in the range MHz
