Alfa ARS-N19 Black 9dBi Indoor Omni Antenna for Stronger Wi‑Fi Coverage

The ARS-N19 is a 2.4 GHz dipole antenna designed for equipment using the 2400–2500 MHz frequency range. Its 9 dBi gain provides a defined antenna option for applications that require operation within this band, while the linear, vertical polarization establishes the intended signal orientation for installation. A 50 Ω impedance allows the antenna to match equipment designed around the same standard impedance, and the specified VSWR of up to 1.5:1 indicates controlled impedance matching across its stated operating range. Connection is provided through an RP-SMA plug, giving the antenna a direct mechanical and RF interface for compatible devices without requiring a different connector type at the antenna itself.

With a slim 13 mm diameter and an overall length of 392 mm, the ARS-N19 uses an elongated dipole form that can be positioned vertically in accordance with its specified polarization. The operating temperature range of -10 °C to +55 °C supports use across the environmental conditions covered by the stated limits, while the humidity rating of 95% at 55 °C defines the level of moisture exposure for which operation is specified. These physical and environmental characteristics help determine whether the antenna can fit the intended mounting area and operate within the planned conditions. Together, its frequency range, gain, impedance, connector type, dimensions, polarization, and environmental limits provide the core information needed to assess compatibility with a target 2.4 GHz installation.
