GRA-3000MII Ultra-Wideband RF Test and Receiving Antenna
A professional instrument-grade receiving antenna covering an immense 2MHz to 3GHz range. Designed for high-precision RF monitoring, EMI testing, and laboratory applications where ultra-wide frequency coverage is essential.
The Ultimate Broadband Sensor for RF Professionals.
The GRA-3000MII is engineered for operators who require a single, compact solution for monitoring the entire radio spectrum. Spanning from 2MHz to 3000MHz, this antenna is a critical tool for RF turnkey manufacturing and electronic testing environments.
Key Applications:
- Spectrum Monitoring and Analysis: Perfectly suited for scanning a wide array of frequencies to detect signal interference or monitor band activity.
- EMI and EMC Pre-compliance: Its sensitive reception makes it an ideal probe for capturing unintended radiated emissions during the product development phase.
- SDR and Receiver Testing: Provides a stable, omnidirectional reference for Software Defined Radio (SDR) setups and wideband receivers.
- Instrument-Grade Design: While primarily a receiving antenna, it supports high-frequency transmission (above 1GHz) for specialized testing scenarios.
Built for Precision and Longevity:
- Compact Fiberglass Housing: The 30cm fiberglass radome provides excellent protection against environmental factors while maintaining a low profile in laboratory settings.
- Professional Connectivity: Equipped with a standard N-Male connector to ensure low-loss signal transfer and secure attachment to high-end RF instruments.
- True Omnidirectional Performance: Capture signals from 360 degrees without the need for constant repositioning, ensuring no signal is missed.
