ALFA ARS-NT5B7 — WiFi 7 Tri-Band Dipole Antenna
Table of Contents
Product Overview#
The ARS-NT5B7 is a tri-band dipole antenna from ALFA Network designed for WiFi 7 (802.11be), with full support for 2.4 GHz / 5 GHz / 6 GHz. Its operating temperature range of -40°C ~ +85°C (industrial grade) far exceeds comparable products (typically -10°C ~ +55°C). The 6 GHz gain of 7 dBi is the highest among the three bands, effectively compensating for short-wavelength indoor attenuation. It currently works with ALFA WiFi 6E adapters (AWUS036AXM / AWUS036AXML), and will be ready for future WiFi 7 adapters as soon as they launch.
Key Features#
- Full WiFi 7 Tri-Band Coverage: All three bands — 2.4 / 5 / 6 GHz — in a single antenna
- Highest 6 GHz Gain: 7 dBi: The highest gain across all three bands, compensates for 6 GHz short-wavelength attenuation
- Industrial-Grade Temperature: -40°C ~ +85°C: Suitable for industrial environments, outdoor enclosures, and demanding deployments
- Omni-Directional Radiation: 360° uniform horizontal coverage, easy installation
- Ultra-Lightweight 20 g: Minimal impact on device thermals, flexible mounting
- Low VSWR ≤ 2.0: Meets spec across all three bands for efficient RF transmission
- Backward Compatible with WiFi 6E / 6 / 5: Ready to use with existing ALFA adapters today
