ANTENNA MAST SLEEVE (P/N 126m101) - New Surplus

The 126m101 antenna mast sleeve (NSN 5985-00-980-9350) supports and protects mast-style aircraft antennas at fuselage mounting penetrations. This component distributes structural loads and provides strain relief at the antenna base, stabilizing the mast during flight operations. Commonly used in VHF communications installations on general aviation aircraft, it reduces vibration and movement that could compromise signal quality or antenna integrity.

Installation should follow FAA AC 43.13-2B guidance and verify compatibility with your aircraft's Illustrated Parts Catalog before mounting.
