Enhanced Performance: </strong>This compact active small magnetic loop antenna is designed to deliver optimal results. With a frequency range from 50kHz to 500MHz, it provides excellent reception capabilities for a wide range of signals.<br /> <strong>2. High-Quality Components: </strong>While the shortwave radio active loop antenna doesn't include a 12V linear power supply, it is recommended to purchase a high-quality power supply separately. This will ensure the antenna operates at its best and maximizes performance.<br /> <strong>3. Versatile Design: T</strong>he full band radio antenna consists of a top jumper board, small loop amplifier board, small loop coil, feeder line, and 12V linear power supply. The top jumper board and small loop feature switchable amplifier boards, allowing for different configurations to suit your needs.<br /> <strong>4. Improved Signal Gain: </strong>The Mobius loop within the active small magnetic loop antenna structure provides a voltage gain twice that of a regular loop, enhancing signal reception. The shielding loop effectively reduces interference caused by surrounding electric fields like static discharge. The non-shielded loop offers a simplified structure.<br /> <strong>5. Easy Installation and Modification:</strong> The active small magnetic loop antenna can be easily replaced with thicker wires, simplifying size modifications. Its straightforward structure and convenient installation process make it user-friendly and accessible for all.<br /> <div> <br /> </div> <br /> <br /><br/><br/><span><strong>Specification:</strong></span><br /> <span>Origin: Mainland China<br /> </span>This little loop antenna works with all radios, SDRs, radio stations, receivers Owning it won't let you down, come and experience it!&nbsp;&nbsp;<br /> Test video: /> <br /> The small loop antenna (hfdloop) is a small-size full-band loop magnetic field active receiving antenna, receiving frequency range of 50kHz to 500MHz, mainly consists of the top jumper board, small loop amplifier board, small loop coil, feeder, feed line and 12V linear power supply, of which the top jumper board and the small loop amplifier board have several sets of switches, by adjusting the position of the switches can be achieved by the small loop antenna of different structures, of which the Mobius loop can achieve the normal small loop antenna, the Mobius loop can achieve the normal small loop antenna. The Mobius ring can achieve twice the voltage gain of a normal small ring; the electric field shielding ring can effectively reduce the interference caused by the electric field of the surrounding environment, such as electrostatic discharge, etc.; the structure of the unshielded ring is simple, and the small ring as a whole can be replaced by a thicker wire, the size of the modification of a simple, easy to set up.<br /> <br /> Small ring antenna technical indicators:<br /> Receiving frequency range: 50kHz to 500MHz<br /> Gain: 17dB@10MHz<br /> Output noise: -125dBm(@10MHz, BW=100Hz)<br /> P1dB: +15.5dBm@10MHz<br /> OIP3: +38dBm@10MHz<br /> Supply voltage: 9V to 12V<br /> Supply current: 130mA to 150mA<br /> Antenna Interface: SMA(M)<br /> Output Connector: SMA(F)<br /> Small ring coaxial cable model: RG402<br /> Small ring coaxial cable loss: 0.145dB/m<br /> Small ring antenna linear length: 60cm<br /> Size: 60*45*18MM/2.36x1.77x0.71inch<br /> <br /> Shipping list for this version of small loop antenna:<br /> 1 x small loop antenna amplifier board.<br /> 1 x headphone jack adapter cable.<br /> 1 x Top Patch Panel<br /> 2 x Small loop coils (RG402 coaxial cable)<br /> 1 x 7 metre feedline<br /> 1 x 1 metre feeder cable<br /> 2 x Sticky Hooks<br /> 1 x EVA Storage Bag<br /> <div> <br /> </div> <p> <strong>Note:</strong><br /> Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
