Wholesale wifi antenna

Buyers must prioritize Frequency Range (2.4GHz, 5GHz, or WiFi 6E/6GHz) to ensure compatibility with target routers. Antenna Gain (dBi) is crucial; higher dBi provides a narrower, longer reach, while lower dBi offers broader, short-range coverage. Additionally, verify the VSWR (Voltage Standing Wave Ratio), which should ideally be <1.5 to ensure high transmission efficiency and minimal signal loss.

The most common connectors are SMA, RP-SMA, and IPEX (U.FL). For external consumer routers, RP-SMA (Reverse Polarity SMA) is the industry standard. For internal PCB mounting or IoT modules, IPEX/MHF connectors are required. Ensure the supplier provides gold-plated connectors to prevent oxidation and maintain signal integrity over long-term use.

For the US market, products must comply with FCC Part 15 regulations. For the EU, CE marking and RoHS/REACH certification are mandatory to ensure the absence of hazardous substances. If sourcing for outdoor use, verify the IP66 or IP67 waterproof rating and UV resistance of the plastic housing (radome) to prevent cracking and water ingress.

Omnidirectional antennas are best for general retail and indoor office environments as they provide 360-degree coverage. Directional antennas (such as Yagi or Panel antennas) are specialized for point-to-point bridges or long-distance outdoor links. B2B buyers should maintain a stock ratio based on these use cases, typically favoring omnidirectional models for high-volume consumer sales.

This is a common risk in wholesale. Always request a Full Chamber Test Report (Anechoic Chamber) from the supplier. Professional manufacturers on Made-in-China.com should provide 2D/3D radiation patterns and gain charts. For large orders, hire a third-party inspector to perform a sample signal strength test before final payment.

Focus on the BOM (Bill of Materials), specifically the quality of the internal copper element versus cheaper aluminum alternatives. Negotiate based on tiered pricing (e.g., 1k, 5k, 10k units). Ask for customized packaging (OEM) and logo printing, which is often included for free or at a low cost once you meet a specific MOQ (Minimum Order Quantity).

Antennas, especially long fiberglass outdoor models, are prone to bending or snapping. Insist on reinforced cardboard tubes or double-corrugated boxes with EPE foam inserts. For sea freight, ensure the use of pallets with plastic wrap to protect against moisture and salt-air corrosion, which can degrade the metal connectors.

Be aware of Section 301 tariffs if importing into the US from China, as telecommunication parts may fall under specific high-tariff categories. Check the HS Code (typically 8517.70) to determine exact duty rates. Utilizing Trade Assurance or secure payment terms on Made-in-China.com helps protect your capital against non-compliance with technical specifications.
