Rfwel Infra Dual Band 2.4/5 GHz Wi-Fi Antenna 7 dBi RP-SMA

Dual-band Wi-Fi replacement antenna

This dual-band antenna replaces the stock whip on routers and access points that use an RP-SMA female jack. It covers the 2.4 GHz and 5 GHz unlicensed bands used by Wi-Fi 4, Wi-Fi 5 and Wi-Fi 6 equipment. The flexible rubber-duck body tilts and swivels so you can orient the element for best coverage. Installation is a simple screw-on swap with no tools required.

Passive element with 7 dBi gain

As a passive antenna it draws no power and adds no fan noise or heat to the system. The 7 dBi figure represents directional gain over an isotropic radiator, concentrating signal toward the horizon rather than boosting total output power. Because it is receive-reciprocal, both transmit range and receive sensitivity improve in the favoured direction. No driver, firmware or configuration change is needed on the host device.

Upgrade for fixed or low-gain stock antennas

The jump is worth it when the supplied antennas are non-removable, limited to 2 dBi or mounted in a metal enclosure that blocks radiation. It also helps when a single access point must reach a distant room or outdoor area without adding a second node. Buyers who need MIMO streams beyond what one element provides, or who require a weather-sealed outdoor radome, should look for multi-element or IP-rated kits instead.
