HFRA 5154 – Transmit Loop Antenna for Calibrations
The transmit loop antenna HFRA 5154 was designed to generate well defined magnetic fields with moderate fieldstrength levels (< 0.1 A/m) in the frequency range 100 kHz to 30 MHz. With slightly reduced performance the loop can be used in the frequency range up to 50 MHz.
The loop, consiting of two turns, is shielded against E-fields. The nickel-plated brass housing contains a toroid transformer (current transformation ratio 2:1) and the termination resistor (max. 0.5 W). The transformer allows very good matching to the widely used 50 Ohm measurement equipment and an extremely flat frequency response over the entire frequency range. The loop can mounted at its female large camera thread.
Both female BNC-connectors are directly wired with each other. One of them can be used to feed the loop, the other can be used to monitor the voltage with a voltmeter (high impedance).
