Product introduction:
- Listening to shortwave radio is an exciting hobby, but for urban residents, the reception experience is often disappointing. We can hardly hear any useful signals, even the signals of relatively strong radio stations. The signals are buried in many different types of interference and hum. Why is this happening? In the past two decades, the level of urban radio frequency interference (RFI) has deteriorated dramatically, and various poorly designed electronic devices have spread to all corners of the city. To a large extent the interference is caused by this. LCD TVs, WiFi routers, poorly designed switching power adapters and power cats, electric car chargers, etc. have seriously polluted the short-wave radio spectrum. If there is a suitable place to set up an outdoor long-line antenna, it will have a good reception effect, but when living in a residential area, a building, or a high-rise apartment, there is no roof to set up a long-line antenna. At this time, I need a receiver suitable for balcony installation. Antenna, MLA-30+ is such an antenna. MLA-30+ is a loop magnetic antenna.
- The MLA-30+ loop antenna is a very 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 the environment of limited urban living areas. Frequency coverage: 500kHz to 30 MHz. Excellent directivity can help you reduce noise and improve signal-to-noise ratio, and can dig out weak signals that are submerged by noise during conventional antenna reception.
- The MLA-30+ loop antenna is easy to set up and can be easily installed on balconies, rooftops and other locations. It is small in size and low-key installation without worrying about opposition from neighbors and properties.
- Another advantage of the MLA-30+ loop antenna is that it is directional. 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.
- Do not connect it to the transmitter, as it will cause damage to the preamplifier
- Compared with long wire antennas, up to 30 dB of local radiated noise suppression
- The figure-of-eight pattern provides deep dummy points to further reduce interference
- Main coverage range: 500kHz to 30 MHz
- USB power supply, easy to get electricity. The built-in feeder simplifies the installation process.
