This primer-quality 9–10 dBi single-polarized indoor directional log-periodic antenna is engineered for high-gain, focused WiFi coverage in warehouses, offices, retail floors, and industrial facilities. Unlike omnidirectional antennas that waste energy in unused directions, this log-periodic design concentrates RF energy into a precise beam, extending reliable connectivity to distant access points, bridges, or client devices while rejecting off-axis interference.
Built to primer-grade quality standards, every unit undergoes rigorous electrical and mechanical validation to ensure consistent gain, VSWR, and build integrity across large wholesale volumes. The single linear polarization (vertical) matches standard WiFi router and AP ports, delivering maximum power transfer without the mismatch losses common with dual-pol antennas on single-port systems.
Covering the full 2.4 GHz (2400–2483 MHz) and 5 GHz (5150–5850 MHz) WiFi bands, it supports WiFi 4/5/6/6E deployments with stable performance across all channels. Designed exclusively for indoor use, its low-profile radome and lightweight construction allow discreet wall or ceiling mounting without structural reinforcement. All units ship pre-certified with CE, FCC, and ROHS, enabling immediate global deployment.

Q: What does “primer quality” mean for this antenna?
A: “Primer quality” denotes our baseline production grade that meets all published electrical/mechanical specs with tight tolerances (gain ±0.5 dB, VSWR ≤1.8:1). It’s validated for high-volume wholesale where consistency matters more than premium features—ideal for MSPs, distributors, and large-site deployments. Higher “pro” grades with tighter tolerances are available on request.
Q: Why choose single-polarized over dual-polarized for indoor WiFi?
A: Most indoor WiFi APs and clients use single vertical polarization. Using a dual-pol antenna on such systems incurs 3 dB mismatch loss because half the transmitted power couples into the unused orthogonal port. Single-pol antennas eliminate this waste, delivering full rated gain to compatible gear—maximizing range and throughput.
Q: Can this antenna be used outdoors if sheltered?
A: While electrically capable, the radome is rated for indoor use only (-20°C to +60°C, non-UV-stabilized). For outdoor/sheltered applications, request our UV-resistant IP67 variant—same electrical specs, enhanced environmental protection.
Q: How does log-periodic compare to patch or Yagi for indoor WiFi?
A: Log-periodic offers wider bandwidth than Yagi (covers full 2.4G+5G without retuning) and more stable gain vs. frequency than patch antennas. Tradeoff is slightly larger size—but for indoor directional links needing multi-band operation, it’s the optimal balance of performance and simplicity.
Q: What mounting height and orientation do you recommend?
A: Mount at 2.5–3.5m height, aimed horizontally toward target coverage area. Vertical polarization requires upright orientation (connector down/up). Avoid metal obstructions within 0.5m of radiating elements. We provide free site-specific placement guides—email floor plans for optimized layout.
Q: Do you provide test reports for wholesale verification?
A: Yes. Every batch includes gain/VSWR test summaries. Full anechoic chamber reports and S-parameter files available for QA validation. We also support third-party lab testing coordination for large contracts.
