Usage Tips:Description The MLA-30+ loop antenna is a popular broadband antenna. It is an effective antenna for short-wave listeners (SWL) and amateur radio enthusiasts (HAM) to receive medium-wave and short-wave in limited living areas. Frequency covers from 100KHz to 30 MHz. Excellent directionality can help reduce noise and improve SNR ratio, and can dig out weak signals that are overwhelmed by noise when conventional antennas are received. The MLA-30+ loop antenna can be easily installed on balconies, rooftops, and other places, featuring compact size. Another advantage of the MLA-30+ loop antenna is that it is directional. By rotating the antenna, the antenna's dummy point is aligned with the interference signal so that the specific near-field interference can be minimized.
