HFRA 5152 – Circular Transmitting Loop Antenna
The passive Loop Antenna HFRA 5152 was designed to generate well defined magnetic fields in the frequency range up to 3 MHz. The signal generator is connected to the loop antennas BNC-input, the second BNC-connector is used to monitor the RF-level using a high impedant voltmeter or an oscilloscope respectively. The loop current is measured as a voltage drop across the built-in 20 Ohm resistor. A measured voltage of 50 mV at the monitoring connector corresponds to a loop current of 2.5 mA. The loop current is strictly proportional to the generated fieldstrength. The fictious electric fieldstrength is 0.01 V/m at a distance of 1.3 m with a monitoring voltage of 50 mV.
