AirVoice GA to U174 Helicopter Plug Adapter — PJ-068 PJ-055 Mono (Not Impedance Matching)

Overview

AirVoice presents a compact General Aviation (GA) to U174 helicopter plug adapter designed to bridge PJ-068 and PJ-055 twin plugs to a U-174 receptacle. The unit features a matte black housing with robust contacts, delivering a clean, practical connection for quick checks, field work, or workshop setup. It emphasizes ease of use in tight spaces and during routine maintenance, without promising performance beyond straightforward connectivity.

Important note: this adapter is not impedance matching and is mono-only. It is intended for simple, direct connections and basic testing rather than high-fidelity signaling or stereo paths.

What it connects

The adapter accepts GA twin-plug inputs PJ-068 and PJ-055 and converts them to a U-174 helicopter plug. It includes two common input sizes—.206 inch and .25 inch jacks—allowing compatibility with standard GA connectors before the U-174 interface.

• GA twin-plug compatibility: PJ-068 and PJ-055
• U-174 helicopter plug output
• Two input sizes: .206" and .25"
• Mono-only signal path
• Not impedance matching

Practical uses

Use this adapter for quick field checks, cockpit setup rehearsals, and basic maintenance tasks on the tarmac or in the hangar. Its compact form fits neatly into tool kits and maintenance benches, making it a practical addition to daily workflows.

• Field testing and bench setups
• Hangar-based maintenance rehearsals
• Training or familiarization with connector types
• Portable, durable design for on-the-go use

The rugged build and matte black finish support repeated connections and disconnections, while the mono configuration keeps the signal path straightforward for everyday tasks.
