RA Miller Industries Inc. (RAMI) has been manufacturing advanced antenna solutions for more than 60 years on platforms including handheld, manpack, vehicular, ground based, airborne, and shipboard applications.
RAMI antennas cover a wide spectrum including HF, VHF, UHF, LS, and C-band. Additionally, RAMI has multi-band antennas covering several functions within a single form factor. By keeping all stages of the design and manufacturing process in house, RAMI has the ability to streamline new product development while maintaining high quality standards.
Airborne antennas for the defence industry
RAMI manufactures many different types of airborne antennas covering a wide range of frequencies, from HF up to 6 GHz. These antennas serve a variety of functions, including communications, glide slope, FM homing, marker beacon, airborne radar interrogation – Identification Friend or Foe (IFF), TACAN, SATCOM and GPS.
RA Miller Industries
We also offer multi-band aircraft antennas that operate at more than one frequency range. All RAMI antennas are designed and qualified in-house to meet the specifications our customers demand.
Radar interrogation antennas for airforce applications
RAMI manufactures several radar interrogation antennas for IFF (identification friend or foe). Our diverse range of form factors offer options from flush mount to aerodynamic, high speed housings for various rotorcraft, and fixed-wing aircraft installations.
Airborne communication antennas
We have developed a wide variety of airborne communication antennas that offer broadband performance with options to cover more demanding power handling requirements. Our designs range from 50W continuous on the RAV30512 antenna up to 1,500W continuous on the AS-3808/ARC antenna.
Glide slope antennas for military aircraft
RAMI manufactures a lightweight glide slope antenna that is designed for use with standard Glide Slope receivers for reliable performance. This antenna can be mounted either in a radome or externally on the aircraft.
RAMI manufactures the AT-640A/ARN, a receive-only antenna that can be used on both fixed-wing and rotary-wing aircraft. This antenna meets the requirements of Military Specification MIL-A-5999 for electrical and environmental performance.
Tactical Air Navigation System (TACAN) antennas
RAMI manufactures TACAN, identification beacon antennas designed for use with Radar Interrogation. This antenna can withstand speeds up to Mach 2 and operates within a temperature range of -55°C (-67° F) to 148°C (300° F).
RAMI GPS antennas are designed specifically to meet FAA TSO-C190 specifications for WAAS GPS requirements. Our AV-801 antenna had been deployed on numerous military platforms upgrading to the ADS-B 2020 requirement. The mounting footprint matches the ARINC 743 standard found on many aviation aircraft up to and including business jets.
RAMI offers a few different SATCOM antennas that can be used on aircraft, as well as, on tactical vehicles. The RAMI8713 is a low-profile SATCOM antenna and the RAMI8715 can go on rotor aircraft. These antennas have frequency coverage to support both Legacy and MUOS UHF communication needs.
