The -30+ loop antenna is a popular broadband antenna, perfect for shortwave listeners and amateur radio operators (HAM) on urban balconies, rooftops, etc.
This portable shortwave indoor loop antenna is a simple kit that includes all necessary parts. Modular design, easy to install in confined spaces such as balconies and rooftops.
Excellent directivity can help you reduce noise and improve the signal-to-noise ratio; you can simply change the antenna's orientation to align the antenna's virtual point with the interfering signal, thereby minimizing specific near-field interference for best results.
Noise suppression is up to 30 dB compared to long-wire antennas. It can dig out weak signals that are overwhelmed by noise. The 8-shaped pattern provides deep virtual points to further reduce interference.
Do not connect to the transmitter as this may damage the preamplifier.
Listening to shortwave radio is an exciting hobby, but for city dwellers, the experience is often disappointing. We could barely receive any useful signal, not even from more powerful radio stations. Signals hide in all different types of interference. Why does this happen? Urban radio frequency interference (RFI) has increased dramatically, and all types of poorly designed electronic devices have been found in every corner of the city. Interference is generated by LCD screens, WiFi routers, poorly designed power adapters, WiFi extenders, EV chargers, etc., all of which together cause interference in the shortwave spectrum. If there was a suitable place to set up an outdoor long-wire antenna, the situation could be different. But when living in an apartment or condominium, there is no roof to set up a long-wire antenna on. That's when you need -30+, a magnetic loop antenna for balcony installations.
