PPM Systems will be exhibiting at this year’s Defence and Security Equipment International (DSEI) trade show. On display will be the UK company’s military RF over fibre system, which provides a way to deploy SIGINT antennas remotely, allowing personnel to remain a safe distance away. The optical transmission ensures immunity to interference from local RF sources. Also featuring on the PPM Systems stand will be a range of magnetic and electric field antennas, the MAC Cellular Survey SDRx System and ViaLite’s commercial RF over fibre system. PPM Systems specialises in military RF over fibre systems and custom RF design. Among its wide range of products are antennas and antenna systems for EW, SIGINT and comms; RF filtering and signal conditioning; RF spectrum receivers and signal generators; and RF over fibre radio extension (Forax). At previous DSEI shows the company has shared a stand with supplier Antenna Research Associates (ARA), but both companies have their own stands this year, due to company growth and increased product ranges to showcase. DSEI is taking place in ExCeL, London, from 12-15 September 2017 and PPM Systems will be on stand S3-242.
