2 CATALOGUE OF WAVEGUIDE HORS Qpar Angus designs and manufactures microwave components and antenna systems, across the radio frequency spectrum from decimetre to submillimetre wavelengths. The range of products includes many types of broad band antennas, duplexers, filters, mixers, high power sources & special components, for use in communication systems, surveillance, radar and electronic warfare, as well as in many industrial and medical applications. This catalogue gives details of the standard range of horn antennas, including precision standard gain horns and wideband and multioctave horns. A measured calibration chart of gain versus frequency is supplied with every horn. Measured radiation patterns can be supplied if required. The horns are usually supplied with integral Type or SMA coaxial to waveguide transitions, but they can be provided with standard waveguide flange inputs. Mounting brackets are supplied as standard. Protective windows can be incorporated as an option. Although this catalogue describes the standard range of horns, the company is always willing to consider unusual requirements for bandwidth, gain and gain slope. All specifications are correct at time of going to press and may change without notice. +44 (0) (0)

3 E E L H Standard Gain Horns These precision standard gain horns are manufactured from brass, copper or aluminium alloy. The horns come in 3 ranges with nominal gains at midband of 10, 1 and 20 i with a spread of about 3 across the frequency band. A calibration curve of gain versus frequency is supplied with each horn. The horns are normally fitted with an integral coaxialtowaveguide transition, but can be supplied with a waveguide flange. Details of horn specifications can be found on the following pages. Mounting brackets are included at no extra cost. on standard gains and frequency bands are also available. +44 (0) (0)

15 2 18 GHz High Gain Horn Antenna Model umber WBH218H/S This high gain high performance ridged waveguide horn, Model umber WBH2 18H/S is ideal for EMI/RFI testing, EMC measurements, wide band spectrum surveillance or materials evaluation etc. The horn covers frequencies used for PC, PCS, GSM, GPS, direct to home salite broadcasting, and many others. It is especially useful for receiving very low signals or transmitting moderate power levels. The horn can be used where a parabolic reflector antenna may previously have been used to increase the gain, or where it is not practical to install a wide band standard reflector antenna. The horn is cheaper than an equivalent feed and reflector antenna assembly. Both Type and SMA versions are available. Special techniques have been incorporated to prevent higher order waveguide modes. The construction is a metal/glass composite. The horn comes with a specially designed weatherproof radome which provides good protection against the elements but has very little loss across the frequency band. A mounting bracket similar to shown is provided at no extra cost. +44 (0) (0)
