MCX-Male to SMA-Female Coax Adapter for SDR Dongles

MCX-Male to SMA-Female Coax Adapter for SDR Dongles

Unlock the full potential of your SDR dongle. This essential adapter converts the tiny MCX port on your Software Defined Radio (like an RTL-SDR) into a standard SMA-Female socket. This allows you to connect a high-performance external antenna for a massive improvement in reception.

💡 Please Note: Sold as a Single Adapter

The main product image shows two adapters from different angles so you can see both connectors. This item is sold as a single (1) adapter.

  • 🔌
    Connector 1: MCX-Male (Device Side): The small "push-on" plug with a center pin that connects securely to the MCX-Female port on your SDR dongle.
  • 📡
    Connector 2: SMA-Female (Antenna Side): Features a center hole and threads on the *outside*. Accepts "Japanese-style" SMA-Male antennas.
  • 📈
    Improve Your SDR Performance: Stop using the stock antenna and connect your dongle to a high-gain discone, dipole, or Yaesu-style handheld antenna.

✅ Compatibility Check

This adapter allows a device with an MCX-Female port to use an antenna with an SMA-Male plug.

  • DEVICES This Fits: Most USB SDR dongles (like RTL-SDR) that use an MCX port.
  • ANTENNAS This Fits: Yaesu, Icom, Signal Stick, and Retevis RT85-style antennas (SMA antenna with a center pin).

⚠️ Check Your Connectors
