Key Features

  • Dual-band support: works with 2.4GHz (802.11b/g/n) and 5GHz (802.11a/n/ac) networks
  • 2-meter extension cable: gives you flexibility to position the antenna away from the router
  • RP-SMA plug: compatible with a wide range of routers and wireless adapters on the market
  • Magnetic base: securely attaches to steel desks, racks, or any ferromagnetic surface
  • 6dBi gain: provides stronger signal reception compared to typical built-in router antennas

Compatibility Guide

The antenna uses an RP-SMA male plug, so it connects directly to devices with an RP-SMA female connector. Many home routers from brands like Buffalo, NEC, ASUS, and TP-Link use RP-SMA connectors, but some compact or mobile routers may use different connector types. Always check your device's connector before purchasing.

Also note that while this antenna supports both 2.4GHz and 5GHz, your router must also support 5GHz to take advantage of that band.

Ideal Use Cases

  • Improving signal in rooms where the router is placed in a corner, closet, or other obstructed location
  • Adding an external antenna to a desktop PC's USB Wi-Fi adapter for better desktop placement
  • Stabilizing the signal of a mesh Wi-Fi node or mobile hotspot
  • Quickly mounting an antenna on a metal rack or steel desk without drilling

Upgrade Considerations

This antenna acts as an external antenna for your router or adapter. It does not improve the router's internal hardware capabilities such as maximum link speed or concurrent device support. Higher gain antennas can be more directional, so you may need to experiment with positioning to find the optimal spot. Try a few different angles and locations for the best results.
