Important Notes
Mono Design :This adapter features a 2‑pole (mono) 3.5mm male plug. It is designed for antenna, FM signal, or other mono audio/rf input. It is NOT suitable for stereo headphones or stereo audio input devices.

Check Your Device Jack :Please ensure your device has a 1/8" (3.5mm) antenna jack (usually labeled “ANT IN” or “FM ANT”), not a 3.5mm stereo audio output port. Incorrect connection may cause signal mismatch.

F‑Type Female Use :This female connector works with standard coaxial cables carrying an F‑type male plug . Do not force any non‑standard connector to avoid damage.

Signal Strength : In areas with weak signal, direct connection to an antenna may still not achieve ideal reception. This product provides only physical connection and does not include signal amplification.

Installation Force :When inserting the 3.5mm plug, align it vertically with the jack and avoid excessive force or rocking, which could bend the internal pin.

Storage & Environment :Keep away from moisture, high temperature, or corrosive environments. When not in use, store in a dry place to prevent oxidation of metal parts.
