Active Mini Magnetic Loop Antenna, 50kHz-500MHz Wideband Small Loop Antenna with Amplifier Board, Broadband RF Receiving Antenna Module

Small ring antenna amplification board and top jumper board 50K - 500MHz

There are several sets of switches on the top jumper board and the small ring amplification board. By adjusting the positions of the switches, different structures of small ring antennas can be achieved. Among them, the Möbius ring can achieve a voltage gain twice that of the ordinary small ring; the electric field shielding ring can effectively reduce the interference caused by the surrounding electric field, such as lightning and electrostatic discharge; the non-shielded ring has a simple structure, and the entire small ring can be replaced by a thicker wire, the size modification is simple, and it is easy to install.
