Features:
The small loop antenna (hfdloop) is a small-sized full-band ring magnetic field active receiving antenna with a receiving frequency range of 50kHz to 500MHz. It mainly consists of a top jumper board, a small loop amplifier board, a small loop coil, a feeder, a feeder and a 12V linear The power supply consists of several sets of switches on the top jumper board and the small ring amplification board. By adjusting the positions of the switches, small ring antennas of different structures can be realized. Among them, the Möbius strip can achieve twice the voltage gain of ordinary small rings; The electric field shielding ring can effectively reduce the interference caused by the electric field in the surrounding environment, such as lightning, electrostatic discharge, etc.; the non-shielding ring has a simple structure, and the entire small ring can be replaced by a thicker wire. The size is simple to modify and easy to erect.
