AV-925 airborne communications


Airborne Communications

The AV-925 antenna was developed to be used with airborne FM transceivers. It is typically used in first responder type aircraft providing a single antenna solution for multiband transceivers. It has met DO-160G, Section 8, Category U requirements for robust vibration and is qualified for installation on helicopters with unknown related rotor frequencies. It is also qualified to perform as a 406 MHz ELT antenna, and is well suited for this function on higher speed, fixed wing aircraft.
