Easat is a proven supplier of commercial, off-the-shelf (COTS) and bespoke equipment. The design and manufacturing facilities featured here introduce Easats extensive capabilities.</p><p>Easat Antennas Ltd, based in Stoke-on-Trent(UK), was founded in 1987 as a specialistprovider of radar antennas and sensors. Sincethat time, Easat has established a reputation asa world-leading supplier of advanced array andreflector antennas for use in radar surveillanceof air, ground and sea targets for airport, port,border security and military applications.</p><p>With over 120 installations worldwide, Easatsreputation for supplying cost-effective, highperformance antennas with proven reliabilityhas led to many end users and consultantsspecifying Easat antennas on their projects.</p><p>With users and customers including FAA(USA),NATS (UK), Transport Canada, Government ofMalaysia, UK MOD, Lockheed Martin andRaytheon, configuring systems with Easatproducts ensures the highest confidence ofachieving performance requirements, on timeand on budget.</p></li><li><p>7/26/2019 Brochure ExhiReg1533299 Easat Main Brochure</p><p> 4/48</p><p>Air Traffic Control Radar Military - Transportable</p><p>2</p><p>Illustrated in the main picture opposite is Easats TacticalDeployable Air Surveillance Antenna. This type of antenna canbe supplied either trailer-mounted or palletised. The antennasystem is self-contained and capable of being transported byship, aeroplane, helicopter or by being towed to site.The design provides for rapid deployment in less than 30minutes from arrival at the operating location.</p><p>The palletised version (shown on opposite page in the deployedmode) has 4-ISO corner locations on the pallet for transportation by standard road transport or purpose-builttrailer. The Trailer version shown below in the transport modehas a weight of 1954 kg.</p><p>The antenna is a dual frequency band, carbon fibre composite-based reflector which operates at S-band (2.7-2.9 GHz) andL-band (1.0-1.1 GHz). Three states of polarisation (linear horizontal, left-hand circular and right-hand circular) areprovided for S-band beam by use of polarisation-switchingcapability. At L-band, the antenna operates in IFF/SSR by useof three beams: sum, difference and omni. These featurescombine to provide leading-edge RF performance from theantenna system.</p><p>Deployment Data</p><p>Design weight of antenna/trailer system 4300 lbs</p><p>Max section weight to lift during erection 72 lbs</p><p>Assembly by 2 persons (wi thout g round anchors) 30 mins</p><p>Operational Capacity</p><p>Max operational wind speed (including gust) 60 knots</p><p>Operating temperature range -40 C to +55 C</p><p>S-Band AzimuthPattern</p><p>S-Band ElevationPattern</p><p>L-Band AzimuthPattern</p><p>Photograph Centre: Easat Trailer-mounted Tactical Antenna, in thetransport modePhotograph Opposite: Easat Pallet-mounted Tactical Antenna, in thedeployed mode</p><p> d B</p><p> d B</p><p> d B</p><p>Angle (degrees)</p><p>Angle (degrees)</p><p>Angle (degrees)</p><p>L-Band ElevationPattern</p><p> d B</p><p>Angle (degrees)</p><p>AzimuthPattern dB</p><p>MainBeam dB</p><p>Aux Beam dB</p><p>Sun Beam dBDiff Beam dB</p><p>Sun Beam dB</p></li><li><p>7/26/2019 Brochure ExhiReg1533299 Easat Main Brochure</p><p> 5/48</p></li><li><p>7/26/2019 Brochure ExhiReg1533299 Easat Main Brochure</p><p> 6/48</p><p>4</p><p>The high-performance Easat EA5325 Primary Surveillanceshaped reflector radar antenna is designed to provide localor terminal area coverage, using a modified cosec 2elevation pattern to in excess of 40 elevation angle.The antenna is suitable for worldwide deployment and offersextreme versatility, being capable of operating with aco-mounted MSSR without the need for a radome, even inharsh icing conditions.
