RF-PRO-1B Active Magnetic Loop Antennas are designed for low-noise reception of signals within the frequency range of 100-kHz to 30-MHz.

Their integral, extra-high dynamic range, low-noise preamplifier is designed for minimum intermodulation distortion in the presence of very high-level signals that would normally overload most preamplifiers.

Installation of the loop on a simple rotator allows the listener to position the loop for maximum rejection of an interfering noise or signal. These receive-only antennas are also a sure-fire way to cover the new 630-meter allocation!

For Amateur Radio operators, AM DXers and Short-Wave Listeners, these active loop antennas are a great way to extend your listening ability. Add RF-PRO-1B Active Magnetic Loop Antennas to your radios and start hearing more signals with less noise

Features

• Primary coverage range: 100 kHz to 30 MHz (50 kHz - 100 kHz with reduced specification)
• A great receive solution for 630 meter band (472-479 kHz)
• Very low IMD, 30 dB Low-Noise Preamplifier insures good performance in both strong and weak signal environments
• Up to 30 dB rejection of locally radiated noise compared to whip antennas
• Figure eight directivity provides deep nulls to further reduce interference
• Rejects power line noise
• Rugged construction, easily mounts to a pole or flat vertical surface
• No manual tuning necessary
• No Home Owners Association problems; low profile and works only 5 ft. above ground level
• Modular design for easy installation and maintenance
• Internal Transmit/Receive keying relay disconnects Antenna/Preamp from your receiver when transmitting
• Same item and improved quality as the old Pixel Technologies RF-PRO-1A and RF-PRO-1B Loops
• NOTE This is a receive-only antenna. DO NOT connect the RF-PRO-1B to a transmitter or the power injector and preamplifier can be damaged
