Desktop 2.4 GHz Antenna

The TP-Link TL-ANT2403N is a 3 dBi omni-directional antenna designed for indoor desktop use. It targets users who need to improve wireless signal strength on compatible 2.4 GHz routers or adapters without installing internal hardware.

Plug-and-Play Installation

The antenna connects via an RP-SMA male plug and includes a 100 cm RG-174 extension cable for flexible positioning. No software or drivers are required, though the fixed cable length may limit placement options in larger rooms or complex layouts.

3 dBi Gain and Coverage

The 3 dBi gain provides a measurable boost for standard 802.11n devices operating between 2.4 GHz and 2.5 GHz. It comfortably handles typical home or small office ranges but runs out of headroom for long-distance links, multi-floor penetration or high-interference environments where higher-gain directional antennas would be necessary.

  • Works with most routers via RP-SMA male connector
  • Flexible placement using 100 cm RG-174 low-loss cable
  • Stable desktop design for indoor deployment

Questions about this item

How can I confirm the TL-ANT2403N is improving my wireless signal after connecting it?

Check the signal strength indicator on your router or adapter; a higher dBm reading or more bars shows the 3 dBi omni-directional gain is working.

What comes with the TL-ANT2403N and what must I supply separately?

The antenna includes a 100 cm RG-174 cable with RP-SMA male plug and a desktop base; you only need a router, access point or adapter with a matching RP-SMA female jack.

Which TL-ANT2403N version suits a 2.4 GHz 802.11n router with three RP-SMA ports?

This single model covers 2.4 GHz~2.5 GHz, offers 3 dBi gain and provides three RP-SMA male connectors designed for 3T3R 802.11n devices.
