<p>1.The -30+ is a toroidal magnetic antenna.</p> <p>2. The -30+ loop antenna is a popular broadband antenna. It is an effective antenna for short-wave listeners () and amateur radio enthusiasts (HAM) to receive medium-wave and short-wave in the limited living area of the city. Frequency coverage: 500kHz to 30 MHz.</p> <p>5.Excellent directionality can help you reduce noise and improve signal-to-noise ratio, and can dig out weak signals that are overwhelmed by noise when conventional antennas are received.</p> <p>4. The -30+ loop antenna is easy to install and can be easily installed on balconies, rooftops, and other small, compact, low-profile installations without worrying about neighbors and property opposition.</p> <p>5. Another advantage of the -30+ loop antenna is that it is directional. By rotating the antenna so that the dummy point of the antenna is aligned with the interfering signal, the specific near-field interference can be minimized.</p> <p>Material: Plastic + Metal</p> <p>colour: As shown</p> <p>Package Contents:</p> <p>1 x Antenna amplifier with 10m feeder</p> <p>1 x Stainless steel vibrator</p> <p>1 x Bias Power Supply</p> <p>1 x USB cable 0.8m</p> <p>1 x 60cm SMA Patch Cord</p> <p>2 x Stainless steel fixing screw</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
