Microwave antenna product

Buyers must prioritize Frequency Range (GHz) to ensure compatibility with specific communication bands (e.g., 6GHz to 80GHz). Key performance metrics include Antenna Gain (dBi), which determines signal strength over distance, and Radiation Pattern Envelope (RPE) to minimize interference. For high-capacity links, verify Cross-Polarization Discrimination (XPD) values of at least 30dB and a low Voltage Standing Wave Ratio (VSWR), typically ≤1.3:1, to ensure maximum power transfer and system stability.

Since these are outdoor installations, ensure the product has an IP67 or IP68 rating for water and dust resistance. The antenna must be rated for Survival Wind Speeds (often 200km/h or higher) and feature anti-corrosion coatings (such as hot-dip galvanization or specialized powder coating) to withstand salt spray in coastal areas. Additionally, check the Operational Temperature Range, typically requiring stability between -45°C and +60°C.

Suppliers must provide evidence of ETSI (European Telecommunications Standards Institute) or FCC (Federal Communications Commission) compliance depending on the target market. For structural safety and quality management, look for ISO 9001:2015 certification. Furthermore, ensure the materials comply with RoHS (Restriction of Hazardous Substances) and REACH directives to avoid customs delays and legal liabilities in strictly regulated regions.

These antennas are primarily used for Point-to-Point (PTP) backhaul in telecommunications networks, connecting base stations to the core network. They are also critical for Enterprise Private Networks, Oil & Gas offshore communications, and Emergency Disaster Recovery where fiber optic deployment is geographically or economically unfeasible. Selecting the right Parabolic Dish diameter (e.g., 0.3m to 3.7m) is essential based on the required link distance.

Always request a Factory Acceptance Test (FAT) report before shipment. For microwave antennas, this should include Return Loss and Gain testing data for each unit. Utilize Made-in-China.com’s Secured Trading services to ensure payment is only released after the goods pass a third-party pre-shipment inspection (PSI) conducted by agencies like SGS or Intertek.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for extended warranty periods (24-36 months) and the inclusion of mounting kits and radomes in the base price. For bulk orders, request tiered pricing where a 10-15% discount is applied when exceeding 50 units, and clarify the Lead Time for customized frequency tuning.

Microwave dishes are highly sensitive to deformation; even a slight dent can ruin the radiation pattern. Insist on reinforced plywood crate packaging rather than standard cardboard. Ensure the Incoterms are clearly defined—CIF or DAP are often preferred for high-value electronics to ensure the supplier handles insurance until the goods reach a major port or your warehouse.

Be aware of Import Duties and Tariffs specific to telecommunications equipment in your country. Check if the supplier's country has a Free Trade Agreement (FTA) with yours to obtain a Certificate of Origin (Form E or Form F), which can significantly reduce or exempt you from import taxes. Always verify that the supplier is not on any restricted entity lists to ensure smooth customs clearance.
