GU4.137.080-01 is a mounting frame designed for installation and securing of transceiver units of the A-037 radio altimeter system.
The frame provides rigid, vibration-resistant attachment of the transceiver inside the helicopter avionics bay and is compatible with A-037-1A, A-037-1V, and A-037-1G unit versions.

The frame is a structural, mechanical component and does not perform any measurement, processing, or electrical functions.
It is used to hold the transceiver on an equipment rack and maintain its stability during flight loads, vibrations, and dynamic operating conditions.

The GU4.137.080-01 mounting frame is used across multiple variants of the A-037 system (including Variant 4, Variant 10, Variant 11 and others) wherever A-037-1 series transceivers are installed.
