Applied EM Offers Anti-Jam Antenna

March 26, 2014By

Applied EM’s anti-jam GPS antenna, AJGPS045, has achieved a four-channel Controlled Radiation Pattern Antenna (CRPA) in a very small size, weight and power (SWAP) particularly suitable for airborne platforms. Its footprint is the same as a standard GPS Fixed Radiation Pattern Antenna (FRPA), the FRPA-3. This is a key enabler to bringing greatly improved anti-jam performance to smaller platforms and... read more
