5.8ghz dish antenna factory

When sourcing from a factory, you must prioritize Antenna Gain (dBi), which directly impacts transmission distance; for 5.8GHz, a gain of 29dBi to 34dBi is standard for long-range links. Additionally, check the Voltage Standing Wave Ratio (VSWR), which should be ≤1.5 to ensure minimal signal reflection and maximum power efficiency. The Front-to-Back Ratio is also vital to reduce interference from behind the antenna, ideally exceeding 30dB for high-density environments.

Ensure the factory uses high-grade aluminum alloy for the dish reflector to prevent corrosion. The surface should be treated with a UV-stabilized powder coating to withstand prolonged sun exposure. For coastal or humid regions, request Salt Spray Test reports (ISO 9227). Furthermore, verify the Wind Load Rating; a professional-grade dish should withstand wind speeds of at least 200 km/h without structural failure.

For international trade, the factory must provide RoHS and REACH certifications to ensure chemical safety. Depending on your target market, FCC (USA) or CE (Europe) compliance is mandatory for the integrated wireless systems. Look for factories with ISO 9001:2015 certification, as this guarantees a standardized quality management system during the manufacturing process.

Most professional factories on Made-in-China.com offer OEM services. You should specify the connector type, typically N-Female or SMA, to match your wireless bridge or radio. Ensure the mounting kit is made of galvanized steel and supports ±15° tilt adjustment for precise alignment during installation.

Request a Radiation Pattern Map and a Network Analyzer Test Report for the specific batch before shipment. For large orders, it is highly recommended to hire a third-party inspection service (like SGS or Intertek) to conduct on-site testing at the factory to verify that the actual gain matches the datasheet.

Start by requesting a sample price which is usually higher, but ask for it to be refunded upon the first bulk order. For volume discounts, aim for a 10-20% price reduction when moving from 100 units to 500+ units. Use the Secured Trading services on Made-in-China.com to protect your payment until the goods are verified.

Dish antennas are prone to deformation if compressed. Insist on reinforced 5-layer corrugated boxes with internal foam bracing or wooden crates for LCL (Less than Container Load) shipments. Ensure the Incoterms are clearly defined; FOB (Free On Board) is generally preferred for buyers who have their own freight forwarders to better control logistics costs and transit times.

Always verify the supplier's Audit Report on Made-in-China.com to check their factory size, production capacity, and business license validity. Use Escrow-based payment methods where funds are only released to the supplier after you provide Proof of Delivery (POD) and initial quality confirmation.
