ALA1530 Aluminium + psu North American

Re-engineered Active Loop Antenna North American Version ALA 1530 (aluminium) with psu

50kHz-30MHz 1m dia. Aluminium Loop

The world famous Wellbrook Active Loop ALA1530 long, medium and shortwave antenna.

This Balanced low impedance Magnetic loop has enhanced performance compared to shielded and Moebius loop types. The unique use of an amplifier to match the loop's reactance is a technological breakthrough in Broadband loop design. See: Comparison of the Mobius Loop verses a Wellbrook loop with an impedance-tracking amplifier using a Vector Impedance Analyser.

Recently re-engineered to increase the LW and MW gain by approx. 10dB and 4dB respectively. The upper HF gain is increased by approx. 5dB. The amplifier intermodulation performance has been improved and an FM band filter is now fitted. A resettable fuse and a power LED are now fitted to the Antenna Interface. Also the interface is fitted with a 200mW power limiter to prevent excessive output if the loop is used very close to a powerful Transmitter. This feature is automatic and does not require additional control wiring.

This unique broadband magnetic antenna is only 1m diameter and rotatable to provide deep nulls to reject noise and interference. Ideal for users with small gardens... This new broadband untuned Loop antenna is the only active antenna designed specifically to reject locally radiated and mains borne noise from TVs, computers, mains wiring etc.

The Loop antenna responds primarily to the Magnetic-Field and rejects locally radiated Electric-Field noise providing far lower noise reception than active whip/dipole antennas. Compared to active whip/dipole antennas, the Loop will reduce locally radiated noise by up to 30dB and mains borne noise by up to 60dB. The ALA 1530 has 30dB nulls to further reduce interference.

It is ideal for small gardens, indoors and directional reception using an antenna rotator.

The ALA1530 offers significant advantages over the traditional tuned Loop, because the Loop can be used away from local interference. Whereas, a tuned Loop has to be positioned next to the receiver where there are high levels of local noise.

This antenna is probably the most advanced broadband active Loop antenna available to the Radio Enthusiast, offering professional performance at an affordable price. The Loop antenna is supplied with an Antenna Interface and a 12 volt regulated Power Supply

An Indoor version, the ALA 1530P with a semi-rigid Loop is also available.
