Yagi antenna factory manufacturers

Buyers must prioritize Frequency Range (MHz/GHz) to ensure compatibility with specific networks like 4G LTE, 5G, or LoRa. Key performance metrics include Antenna Gain (dBi), where higher values indicate better long-range directional performance, and the Front-to-Back Ratio, which determines interference rejection. Additionally, verify the Voltage Standing Wave Ratio (VSWR); a value below 1.5 is ideal for minimizing signal loss and protecting transmission equipment.

Since Yagi antennas are primarily for outdoor use, ensure the factory uses high-grade Aluminum Alloy (6063-T5) or Stainless Steel for the elements to prevent corrosion. The boom thickness should be sufficient to withstand local wind loads. For harsh environments, look for anodized finishes or UV-resistant ABS radomes that protect the active elements from oxidation and extreme weather conditions.

A reputable factory should hold ISO 9001:2015 for quality management. For international trade, products must meet CE and RoHS standards for the European market, and FCC certification for the United States. If the antennas are used in hazardous environments, check for IP66 or IP67 waterproof ratings to ensure long-term operational stability.

Yes, professional factories often provide OEM/ODM services. You can request customization of the element count to adjust gain, specific connector types (N-Female, SMA, or TNC), and cable lengths. For large-scale B2B projects, ensure the factory can provide Simulation Reports (HFSS) and Anechoic Chamber testing data to verify custom designs before mass production.

Utilize Secure Payment Services provided by reputable platforms like Made-in-China.com to ensure funds are only released upon proof of shipment. Always request a Pre-shipment Inspection (PSI) by a third party to verify that the technical gain and material specifications match the proforma invoice.

Start by requesting a tiered pricing structure; typically, a 15-25% discount is achievable when moving from sample quantities to bulk orders of 500+ units. If you are a first-time buyer, negotiate a lower MOQ for the initial trial order by highlighting your long-term distribution potential and market reach.

Yagi antennas are prone to bending during transit. Insist on reinforced packaging, such as thickened cardboard tubes or wooden crates for long booms. To reduce Volumetric Weight charges, ask the factory if the antenna can be shipped in a knock-down (KD) format, where elements are detached and easily reassembled by the end-user.

Check the HS Code (typically 8517.70) for specific import duties in your country. Be aware of Anti-dumping duties or specific telecom licensing requirements (such as WPC in India or ANATEL in Brazil) that may require the factory to provide additional technical documentation for customs clearance.
