Dual-pol Dish Antenna (BBT-3638PM21R04-N2) is a high-performance 21dBi parabolic antenna engineered for 3.4-3.8GHz WiMAX and fixed wireless access networks. Utilizing a ±90° dual-polarized design, this antenna maximizes link capacity and minimizes signal interference for long-distance point-to-multipoint (PMP) transmission.
The BBT-3638PM21R04-N2 dual-polarized dish antenna offers a reliable RF solution for communication engineers and system integrators deploying high-speed wireless networks. Manufactured with a durable aluminum alloy radome, it delivers stable coverage and resilient outdoor performance in demanding project environments.
Why Choose Dual-Polarized Design?
Operating dual polarizations simultaneously allows communication networks to double their data throughput compared to standard single-polarized hardware. The ±90° configuration ensures strong isolation and excellent anti-interference capabilities. This enables clean signal reception across crowded RF bands, making the dual-pol dish antenna an ideal choice for high-capacity backhaul and multi-node access networks.
