Product Overview
#The ARS-25-57A is a dual-band paddle (paddle-style) omni-directional antenna from ALFA Network, supporting both 2.4 GHz (5 dBi) and 5 GHz (7 dBi) simultaneously. Its flat wide-blade form factor uses an omni-directional radiation pattern for 360° uniform horizontal coverage — no aiming required, perfect for placement at the center of a desk. The RP-SMA Male connector directly replaces the factory antennas on all ALFA dual-band adapters.
Key Features
#- Paddle Flat Design: Larger cross-section than traditional round dipole antennas for better low-frequency radiation efficiency
- 5 GHz 7 dBi Gain: Effectively compensates for 5 GHz range attenuation loss
- Omni-Directional Radiation: 360° uniform horizontal coverage, no aiming needed
- Direct Plug-In Replacement: RP-SMA Male connector, directly replaces factory antenna
- Full 5 GHz Channel Coverage: Covers 5.1 ~ 5.9 GHz (including DFS channels)
- Use Cases: Desktop office, remote work — stable dual-band connectivity for everyday use
