What this antenna does

This RP-SMA antenna connects to a wireless router or desktop card to boost signal strength and range. It operates on 2.4 and 5GHz bands and supports 802.11 standards for broad compatibility. The omni-directional design means it works in all directions without aiming. It suits anyone needing better WiFi coverage from existing equipment.

Build and daily fit

The black dipole measures 4.25 inches long and uses an RP-SMA Female connector that twists onto compatible routers, printers or AV receivers. Its adjustable joints let you position it around obstacles or tight rear-panel spaces. No software or drivers are required, so installation takes seconds. The simple mechanical fit works with a wide range of networking gear.

Heat, noise and power

This passive antenna draws no power and adds no heat or noise to your system. It relies entirely on the radio in the host device, so thermals and acoustics stay unchanged. There are no active components to fail or generate interference. It simply extends the reach of the signal already being produced.

Questions about this item

Does the RP-SMA connector limit the antenna to WiFi 2 bands or can it pass newer standards?

The RP-SMA connector passes 2.4 GHz and 5 GHz signals and the antenna is compliant with 802.11b/g/n/ac/ax/be, so it supports WiFi 2 and newer protocols.

What clearance does the 4.25" antenna need behind the router for the RP-SMA female thread?

Allow at least 4.25 inches of straight back-space plus room for the knurled collar to turn; the joint adds roughly another half-inch beyond the tip.

Which way should the RP-SMA collar be turned during installation to avoid cross-threading?

Align the antenna straight, turn the collar clockwise by hand until it seats, then give a light fingertip snug — do not use tools or force the first turn.
