Handheld Active Directional Antenna CHA200 is lightweight, easy to assemble, safe, and portable. It features wide frequency coverage (4 standard modules support 9kHz-3GHz, optional module covers 500MHz-8GHz), high test sensitivity, and excellent directivity.
The CHA200 operates across four frequency bands:
• 9 kHz – 20 MHz
• 20 MHz – 200 MHz
• 200 MHz – 500 MHz
• 500 MHz – 3 GHz
An optional high-frequency directional antenna module upgrade supports 500 MHz - 8 GHz, covering the entire civilian frequency spectrum. Equipped with an N-type connector, the antenna interfaces directly with spectrum analyzers and receivers. All band modules are compatible with the handheld grip without individual tuning, streamlining testing procedures.
The CHA200 integrates a Low Noise Amplifier (LNA) that significantly enhances weak signal measurement capability. Powered by easily replaceable AA batteries, the LNA is automatically bypassed in passive mode with no supply voltage, eliminating safety risks.
