ALFA APA-M04 — 2.4 GHz Indoor Panel Antenna
Table of Contents
Product Overview#
The APA-M04 is a 2.4 GHz indoor panel directional antenna from ALFA Network, delivering 7 dBi gain — significantly higher than standard dipole antennas (typically 2–3 dBi). Its flat panel structure concentrates signal energy in a specific forward direction, making it ideal for enhancing 2.4 GHz coverage quality in office corners, hallways, and other targeted areas. The PR-SMA PLUG connector is a direct replacement for the factory antenna on all ALFA USB Wi-Fi adapters — no adapter needed.
Key Features#
- Single-band 2.4 GHz High Gain: 7 dBi gain offers substantially greater coverage range than standard antennas (2–3 dBi)
- Directional Panel Design: Energy focused forward, ideal for boosting signal in a specific direction
- Desktop / Wall-Mount Dual Use: 61 × 173 × 145 mm, can stand upright or be mounted on a wall
- Wide Temperature Range: Operating temperature -10°C ~ +55°C, suitable for year-round indoor use
- Low VSWR ≤ 2.0: Minimal reflection loss, high RF energy transfer efficiency
- Plug-and-Play: PR-SMA PLUG (= RP-SMA female) standard connector, compatible with all ALFA adapters
