The Electro Magnetic Field (EMF) antenna is a small, high quality passive wide band antenna for the 100 kHz - 30 MHz frequency range. The antenna responds to the electrical- as well as the magnetic field component of radio waves. The EMF antenna is only 5 metres long, with 5 metres lead-in coaxial cable to the receiver. The lead-in coax is also used as counterpoise for the antenna. A connection to ground is therefore not required. A special matching network ensures that the antenna is low- impedance and makes it possible to connect the antenna directly to the 50 ohm antenna input of the receiver, without an antenna tuner. In the central module the received signals are transferred to the receiver by means of a magnetic field. This Magnetic Transfer technology acts as a screen of Faraday, which results in reduced atmospheric noise and interference, caused by statics. The reception with an EMF antenna is therefore quieter compared to a normal wire antenna with direct connection to the receiver. The EMF antenna can be used indoors as well as outdoors and is ideal for low- and medium cost receivers such as the Lowe HF 150, AOR AR 3030, Yeasu FRG 100, Realistic DX 394, AKD HF 3 and portables with external antenna input.
