Product Detail

Feature highlights:The ONWA Ship Boat Radome Radar features a slotted waveguide array antenna with horizontal polarization, supporting X-band frequency (9410 ± 30MHz). It offers adjustable rotation speeds for short, medium, and long ranges, ensuring precise navigation. With a peak output power of 4kW and wind resistance up to 100 knots, it guarantees reliability in harsh marine environments. The radar includes automatic or manual tuning, FET switching modulation, and operates within -25 to +70°C temperature range.

Supplier highlights:This supplier mainly exports to Qatar, Philippines, and Italy, with high customer satisfaction and a positive review rate of 91.1%
