1X(Description: The small loop antenna (hfdloop) is a small size full band ring magnetic field active receiving antenna
To 500MHz, mainly composed of top jumper board and small ring amplifier board. Feeder and 12V linear power supply, in which the top jumper board
Switch, different functions can be realized by adjusting the position of the switch. The loop can achieve twice the voltage gain of small loop
The electric field shielding ring can effectively reduce the interference caused by the electric field in the surrounding environment, such as-
The structure of unshielded ring is simple, and the whole small ring can be replaced by a thicker conductor
