Alfa ARS-N19M 2.4GHz 9dBi Magnetic Dipole Antenna RP-SMA for Wi‑Fi Adapters

The Alfa ARS-N19M combines the ARS-N19 2.4 GHz dipole antenna with the ARS-AS01 magnetic docking base, creating a flexible antenna setup for compatible wireless equipment. The antenna operates across 2400–2500 MHz and provides 9 dBi gain with linear, vertical polarization and 50 Ω impedance. It uses an RP-SMA connector and is suitable for Wi-Fi adapters equipped with a matching RP-SMA interface, including Alfa AWUS036H, AWUS036NH, AWUS051NH, and AWUS036NEH models. The magnetic base includes a 1.5 m cable, allowing the antenna to be positioned away from the connected device when a different placement is more convenient. Its slim 13 × 392 mm form supports straightforward placement in desktop or similar installations.

By providing higher antenna gain, the ARS-N19M can strengthen outgoing wireless signals and improve reception of incoming signals, helping maintain clearer and more reliable short-range communication. Better signal quality can reduce retransmissions caused by weak or incorrectly received data, making the connection more consistent in locations where additional signal reach is needed. The antenna can be used in home and company wireless networks, including remote or difficult-to-reach areas, storage facilities, wireless hotspots, and public spaces where extending network coverage is desirable. It is specified for operation from -10 °C to +55 °C and up to 95% humidity at 55 °C.
