HIGH-GAIN WAVEGUIDE PARABOLIC SOLUTIONS

Dish Antennas (DF)

The DF Series represents FT-RF's flagship microwave parabolic dish antenna architecture, engineered for ultra-long-range point-to-point backhaul and high-power RF transmission across 3.9 GHz to 5.9 GHz. Combining a precision WR-187 waveguide-to-coaxial feed system with a perforated aluminum mesh reflector, this architecture delivers extreme directional gain (29 to 32 dBi), razor-sharp 4° beamwidth, and 300W continuous-wave power handling while dramatically reducing wind load.

* Constructed from corrosion-resistant 5052 aluminum alloy and validated via 96-hour salt-spray testing, the DF Series ensures mission-critical outdoor reliability. Custom reflector diameters, waveguide bands, and polarization configurations are available upon request.

📡 Core Performance & Engineering Excellence

WR-187 Waveguide Feed

Integrated waveguide-to-N-Female feed assembly minimizes insertion loss and supports up to 300W CW and 1 kW peak RF power.

4° Pencil-Beam Precision

Delivers 29 to 32 dBi high directional gain with ultra-narrow 4° horizontal and vertical beamwidths to eliminate co-channel interference.

Low-Wind-Load Mesh Dish

Perforated 5052 aluminum parabolic reflector (~8 kg) significantly lowers wind resistance and structural mast loading in exposed sites.

96-Hr Salt-Spray Proven

Finished with industrial anti-corrosion baked coating and precision CNC mounts engineered for harsh coastal and outdoor environments.
