The MLA-30+ (plus) loop antenna is compact in size, which makes it convenient and stable to set up, can be installed on balconies, rooftops, and other places easily. 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 to receive medium and short-wave. Frequency coverage is from 0.1MHz to 30 MHz. You can have a try. Outstanding directionality can help reducing noise and improving SNR ratio, and can dig out weak signals that are overwhelmed by noise when the conventional antennas are received. By rotating the antenna so that the dummy point of the antenna is aligned with the interference signal, the specific near-field interference can be attenuated to the maximum.
