АMR-0.38B Airborne VHF/UHF antenna
AMR-0.38B antenna is intended for electromagnetic waves receiving and emitting in 30 to 400 MHz frequency range. AMR-0.38B antenna can be installed on helicopters and subsonic aircraft.
Antenna has two configurations:
- AMR-0.38BV – for installation on the aircraft with antenna fairing up relative to its base;
- АMR-0.38BN – for installation on the aircraft with antenna fairing down relative to its base.
