2 port Ku band feed assembly, One Tx port, Linear Polarised, One Rx port, Linear Polarised, Rx and Tx interface, WR75 (WG17) waveguide.
Customer demand led to the development and supply of a 2 port Ku band feed design suitable for Elite and other manufacturer’s satcom antennas.
The new Elite Antenna Ku transmit / receive band 2 port Hybrid Feed and OMT assembly is designed for linear polarisation Ku band signals across the whole of the Ku satcom transmit and receive bands (10.5 – 14.5 GHz).
The feed assembly design provides excellent cross polar performance and very low side lobe levels when combined with a suitable reflector. The feed is designed for use with Elite's wide range of prime focus reflectors, providing efficient illumination and outstanding overall performance. The modular design allows for different f/D values that can be designed to suit the customers’ particular requirements.
The OMT is optimised to give superior return loss over the Super Extended Ku band (10.5 – 14.5 GHz); the isolation is particularly excellent and can be increased further with a transmit reject filter. The hybrid mode feed design provides nearly equal beamwidths to more efficiently illuminate a reflector, this has the benefit of providing a higher cross polar isolation compared to a standard feed.
The feed is designed to match Elite Antennas’ prime focus reflectors with an f/D of 0.34 - 0.42, but versions can also be offered for offset reflectors with a f/D of 0.6 and 0.8. Two WR75 (WG17) waveguide flanges are used as the mechanical interface to the LNB, etc. Elite is keen to work with its customers to provide turnkey solutions to standard and custom antenna requirements.
