Active Loop Antenna Model ALA 1530
150kHz-30MHz 1m dia. Aluminium Loop

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

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 Short Wave Listener, offering professional performance at an affordable price. The Loop antenna is supplied with an Antenna Interface and a 12 volt regulated Power Supply (UK only).

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

Large Aperture Active Loop Antenna Model ALA100
50kHz to 30MHz.

The Wellbrook Large Aperture Loop ALA100 is a specialists antenna designed for the long wave and medium wave DXer.

The antenna uses a 20m circumference thin wire loop to provide optimum S/N. The ALA 100 uses the similar interference reduction properties as the ALA1530.

Universal Magnetic Balun UMB130

The Wellbrook UMB130 is a receiving antenna balun with a 9:1 impedance ratio.

The feeder winding is isolated from the antenna to reduce mains borne noise and antenna/feeder interaction. The UMB 130 allows for Longwire (6-20m) and dipole antennas to use a coaxial feeder cable without an antenna tuner. The UMB 130 has a frequency range of 100kHz to 30MHz and can provide up to 20dB reduction in mains borne noise compared to traditional single ended Baluns.

A special version, the UMB T2FD as available with an integral 500 ohm termination resistor to simplify the antenna construction - see below.

4 way active splitter AS1030

The Wellbrook 4 way active splitter.

RF Pre-Amplifier

The RF Pre-amplifier was originally developed for the increasing the LF and MF sensitivity of the Wellbrook K9AY directional antenna system, thus meeting the demanding requirements for the MW, Topband and LW DXer. This amplifier is also available for home construction of the K9AY antenna and other similar applications.

The Wellbrook Phased Array

The most advanced and totally new receiving antenna designed for optimum MW reception.

The only Broadband Phased Array to offer a uni-directional pattern similar to the Beverage, over 360 degrees with electronic Null Steering.
