The WL E3C Waveguide Horn Antenna is a directional microwave antenna engineered for precise signal transmission and reception across multiple frequency bands. Built from corrosion-resistant 316 stainless steel with epoxy coating, it delivers linear polarization and consistent gain performance in test, measurement, and communication systems.
Technical Specifications
Electrical Performance
• Gain: 10 dB, 15 dB, and 20 dB standard values; custom gain available
• Gain variation: ±1.5 to ±2.0 dB typical
• VSWR: Maximum 1.15:1 (standard gain models); average less than 1.6:1 (others)
• RF power handling: Dependent on waveguide size and interface type. WR-62 examples: 1.4 kW CW, 460 kW peak without coaxial adapters; coaxial-equipped models limited by connector rating
• Frequency ranges: 0.75–1.12 GHz, 1.12–1.70 GHz, 1.45–2.20 GHz, 1.70–2.60 GHz, 2.20–3.30 GHz, 2.60–3.95 GHz, 3.30–4.90 GHz, 3.95–5.85 GHz, 4.90–7.05 GHz, 5.85–8.20 GHz, 7.05–10.0 GHz, 7.00–11.0 GHz, 8.20–12.4 GHz; models available to 40 GHz, 50–75 GHz, and 140 GHz
Physical Characteristics
• Polarization: Linear
• Construction: 316 stainless steel with epoxy coating
