Circular transmit loop antenna HFRA 5146 produces defined magnetic fields in the frequency range from DC to 200 kHz as well as at 15 MHz. It is tuned to resonance at 15.0 MHz.
The loop consists of two circular windings and is shielded against electrical fields. The input impedance has been adjusted to match 50 Ω at 15 MHz.
