Did you know that most CATR feeds reach only approximately 40% bandwidth?

Our Ultrawideband Dual Linear Polarized CATR Feed pushes this performance to nearly 74%, operating across a broad frequency range from 2.3 GHz to 5.0 GHz. This extended bandwidth enables more accurate, flexible, and efficient antenna measurements.

Key technical highlights:

• Rotationally symmetric radiation pattern
• Excellent amplitude taper stability (±2.0 dB over frequency and ±0.5 dB within Theta ±8º)
• High polarization purity with cross-polar discrimination >35 dB at boresight and >30 dB within Theta ±8º
• Dual linear polarization with high port isolation (>35 dB)
• Stable gain performance (13 ±0.5 dB at center frequency)
• Low VSWR (< 2.1:1)

Designed for high-performance CATR systems, this feed supports demanding measurement applications where bandwidth, polarization purity, and pattern symmetry are critical. Its combination of wide bandwidth, stable radiation pattern, and excellent polarization characteristics makes it ideal for precise and reliable antenna testing across multiple sectors, including telecommunications, aerospace, and defense.
