When selecting antennas for long-range Point-to-Point (PtP) or Point-to-MultiPoint (PtMP) links, you must prioritize High Gain (dBi) and Directionality. For distances exceeding 10km, look for Dish Antennas with at least 30dBi gain. Ensure the antenna supports MIMO (Multiple Input Multiple Output) technology, specifically 2x2 or 4x4 configurations, to maximize throughput. Additionally, verify the Frequency Band compatibility (e.g., 2.4GHz, 5GHz, or 60GHz) to match your existing Ubiquiti radios like Rocket or airFiber series.
In environments with high RF noise, focus on the Front-to-Back Ratio and Beamwidth. A higher front-to-back ratio ensures the antenna ignores interference coming from behind the dish. Seek antennas with Integrated Isolation Shielding or 'Symmetry' designs that reduce side lobes. Polarization (Dual-Linear or Slant) is also critical; using a 45-degree slant polarization can significantly improve the Signal-to-Noise Ratio (SNR) in congested urban areas.
Outdoor antennas must withstand harsh weather. Ensure the product has an IP67 waterproof rating and a Wind Survivability rating of at least 200 km/h. For international trade, verify CE, FCC, and RoHS certifications. If the deployment is near coastal areas, confirm the use of Salt Spray Resistant coatings and Stainless Steel mounting hardware to prevent corrosion and structural failure over time.
Check the Connector Type, typically RP-SMA or N-Type. Many Ubnt-compatible antennas feature a Plug-and-Play integration slot specifically designed for Rocket radios. Confirm that the VSWR (Voltage Standing Wave Ratio) is less than 1.5, which ensures efficient power transfer from the radio to the antenna and prevents damage to the active equipment.
The primary risk is Signal Gain Inflation, where suppliers claim higher dBi than the physical hardware can provide. Always request Antenna Pattern Lab Reports or gain test data. Another risk is Counterfeit Branding; ensure you are purchasing 'compatible' antennas from reputable manufacturers on Made-in-China.com rather than unauthorized 'OEM' units that may violate intellectual property rights or fail to meet performance specs.
Focus on Tiered Pricing based on Volume and Sample Validation. Request a Paid Sample first to conduct a field test for signal alignment and throughput. Negotiate for Spare Parts (2-3%) such as pigtail cables and mounting brackets to be included in bulk orders, as these are low-cost for the supplier but critical for your installation teams.
Large dish antennas are prone to Deformation during transit, which ruins their parabolic focus. Insist on Reinforced Plywood Crating or double-walled corrugated boxes with Custom Foam Inserts. For bulk orders, Sea Freight (FOB) is most economical due to the high volumetric weight, but ensure the supplier provides a Detailed Packing List to facilitate smooth customs clearance regarding telecommunications equipment.
Utilize Trade Assurance services provided by Made-in-China.com to protect your payment until delivery. For large-scale infrastructure projects, hire a Third-Party Inspection service (like SGS or Intertek) to perform a Pre-Shipment Inspection (PSI), focusing on material thickness, coating quality, and connector tension.
