2-Pack Mono Audio Adapter

This 2-pack converts an F-type female coaxial connector to a 3.5 mm male mono plug. It suits portable radios and other devices that require an F-to-3.5 mm antenna connection. The adapters use nickel-plated brass and zinc construction for stable signal transmission. They are designed for coaxial network applications.

Sustained Signal Transmission

Nickel-plated brass and zinc contacts maintain consistent conductivity during continuous use. The commercial-grade F-series design resists degradation in permanent coaxial network installations. Mechanical retention stays secure without signal loss over time. No active components are present to introduce thermal drift.

F-Type Coaxial Interface Limits

The F female connector accepts RG6 and RG59 coaxial cables only. Mono wiring carries a single audio channel, so stereo signals are not supported. The 3.5 mm male plug fits standard mono antenna inputs but will not carry a balanced or stereo connection. Bandwidth is limited to the audio frequencies used by FM antenna inputs.

Questions about this item

Will the nickel-plated brass and zinc housing get hot or draw extra power when I leave the adapter connected to my radio all day?

No, the adapter is a passive metal connector with no active electronics, so it generates no heat and consumes no power during continuous use.

My portable radio has a 3.5 mm FM antenna input — do I need any extra cable or tool to use this adapter?

You only need a standard RG6 or RG59 coaxial cable with an F-type male plug; the adapter screws onto that cable and plugs directly into the 3.5 mm jack.

I still use an older RG59 coaxial feed — will the F-type female jack on this adapter accept that cable?

Yes, the F-type female jack is compatible with both RG59 and RG6 coaxial cables, so your existing RG59 feed will connect without an additional adapter.
