Active Loop Antenna Magnetic Loop Antenna for HF AM FM VHF UHF SDR Receiver

Description: Description 50K-500MHz Small Active Loop Antenna Magnetic Loop Antenna for HF AM FM VHF UHF SDR Receiver Description: The small loop antenna is a full-band magnetic active receiving antenna. Its maximum receiving frequency is 500MHz. It is mainly composed of top jumper board, small ring amplifier board, feeder and 12V linear power supply. Different functions can be realized by adjusting the position of the top jumper board switch. The Mobius loop can achieve twice the voltage gain of the ordinary small loop. The electric field shielding ring can effectively reduce the interference caused by the electric field in the surrounding environment, such as lightning. Moreover, the structure of unshielded ring is simple, and the whole small ring can be replaced by a thicker conductor. It is quite easy to erect. The installation and connection mode of small loop antenna is shown in the figure below. Antenna Small ring enlarged plate Top jumper board Different junctions can be realized at different positions, in which Mobius ring can realize twice the voltage gain of ordinary small ring static electricity. Technical Specifications: - Receiving frequency range: 50KHz to 500MHz - Gain: 17dB at 10MHz - Output noise: - 125dbm (at 10MHz, BW = 100Hz) - P1dB: +15. 5dBm at 10MHz - OIP3: + 38dBm at 10MHz - Supply voltage: 9V to 12V - Power supply current: 130mA to 150mA - Antenna interface: SMA (M) - Output interface: SMA (F) - Small ring coaxial cable model: rg402 - Loss of small ring coaxial cable: 0.145db/m - Small loop antenna diameter: 60cm/23.6" - The small ring as a whole can be replaced by a thicker wire, as shown in the figure below Note: - It is only for RX. Not for TX. - Other items pictured are not included, for demonstration purposes only. Thank you for your understanding! The small loop antenna consists of a small loop amplifier, a feeder and a top jumper board, two small loop coils (rg402 coaxial cable), one 5m/16.4ft feeder, one 1m/3.3ft feeder, one 12V linear power supply and 2 traceless adhesive hooks. The amplification board of the small loop antenna adopts the low-noise amplification of the improved version lz1aq. The bandwidth is from 50KHz to 500MHz, the gain is greater than 10dB, and has low bandwidth. The input impedance (1.2Ω at 1MHz) effectively reduces the electric field interference. 12V linear power supply, with current not exceeding 150mA. The specific test curve of the amplification board is shown in the figure below: References: 1. https://vaedrah.angelfire.com/antenna.htm 2. http://www.lz1aq.signacor.com/docs/wsml/wideband-active-sm-loop- antenna.htm 3. https://airspy.com/youloop/ 4. https://www.g8jnj.net/moebius-loop-antenna 5. https://www.g8jnj.net/loop-inductance Payment Terms 1.
