Loop Antennas - Active

• Wideband Precision (9 kHz – 30 MHz): Delivers ±1 dB antenna factor stability across the full frequency range.
• Long-Life, Low?Noise Operation: Internal NiMH battery pack provides >12 hours of noise-free measurements.
• Dual-Field Capability: Supports both magnetic (–31.5 dB Ω·m) and “fictive” electric (20 dB/m) field measurements with one probe.
• Rugged, User-Friendly Design: Milled aluminum housing with LED overload indicator and versatile tripod or handle mounting.

• 8 kHz – 30 MHz Wideband: Delivers ±1 dB antenna-factor accuracy across the full spectrum.
• Dual-Mode Measurement: 20 dB/m (E-field) and –31.5 dB Ω·m (H-field) in one compact probe.
• Long-Life Battery Operation: NiMH pack provides over 12 hours of low-noise, mains-free measurements.
• Overload Protection: Built-in LED indicator alerts you at the 1 dB compression point.

• Nominal frequency range: DC - 1 kHz
• Nominal measuring range: 0 - 7000 A/m
• Extended measuring range: 0 - 9000 A/m
