The MLA-30 Shortwave Loop Antenna is an affordable active loop antenna will be of great benefit to those shortwave listeners who are unable to erect an outdoor antenna. The MLA-30 Shortwave Loop Antenna can be mounted indoors on any non conductive rod or tube, such as PVC conduit or fibreglass rod.
The loop element of the MLA-30 Shortwave Loop Antenna has a design diameter of 60cm and is connected to the active amplifier housing by two stainless steel wing nuts.
The antenna is supplied with a “bias tee” power injector and derives the DC voltage (12v) necessary for operation from any USB power supply or power bank.
Despite criticism of the USB components adding RF noise to the system, the power injector is well filtered and there is no discernable difference between using this setup when compared to a 12 volt linear power supply and separate bias tee.
The MLA-30 Shortwave Loop Antenna provides good performance between 500kHz and 30 MHz, and can be rotated to optimise reception. This is particularly useful on the MW broadcast band where adjacent stations can be nulled out to improve the listening experience.
Shortwave performance has been favourably compared to units costing 4 times as much as the MLA-30 Shortwave Loop Antenna. The Tecsun Radios Australia MLA-30 Shortwave Loop Antenna is supplied with both an SMA to BNC adaptor and a BNC to 3.5mm adaptor to ensure compatibility with all modern shortwave receivers.
