Intelligence Surveillance Reconnaissance Antenna (ISR)

JEM Engineering designs and builds a wide range of products for SigInt and ISR applications. We offer antennas covering the frequency spectrum from 2 MHz to 40 GHz, including a number of HF, UHF, and VHF antennas designed specifically for airborne platforms. JEM has expertise in compact, lightweight antenna design of beamformers and multi-band arrays, plus the experience and tools to optimize our antenna solutions to specific missions and platforms. We produce a number of antennas that are suitable for use individually, and are also ideal for use in multi-antenna arrays for Direction Finding and Geolocation.

Communication Antennas

JEM Engineering offers cutting edge antennas designed for communications, such as rugged man-portable antennas, vehicular Comms antennas, and SATCOM antennas. We produce a variety of flight-qualified airborne Comms antennas covering frequencies including UHF, VHF, L-Band and SATCOM, among others. JEM’s design engineers have developed antennas from 2 MHz to 40 GHz. Our in-house high speed RF testing capabilities enable us to capture real world interaction effects between a human body and a radio antenna, and that data enables us to build antennas that perform just as well on the mission as they do in the lab.

Security Antennas

JEM Engineering produces antennas for use in various security applications, including in place monitoring, bug sniffing and covert communications. We specialize in low-profile, ultra-wideband receive antennas that can be handheld, mounted in stationary locations, or on vehicles. JEM’s suite of antennas covers the frequency spectrum from 2 MHz to 40 GHz, and includes omni antennas that can each receive signals over such broad bands as 20 MHz to 18 GHz. We offer many antennas that can be arrayed for Direction Finding and Geolocation applications, or used individually as sensors.
