Narda IDA Directional Loop Antenna 1, 3100/11 | 20 MHz - 250 MHz

The Narda IDA Directional Antenna 1, 3100/11 is a light and easy-to-use loop antenna that covers a frequency range of 20 MHz to 250 MHz. IDA Directional Loop Antenna 1 models include the ISM band at 27 MHz and are tailored for interference and spurious signal searching in the VHF broadcast radio range.The Narda IDA also covers the lower end of VHF television and includes DAB frequencies. Narda Safety Test Solutions has specially optimized the antenna design to generate a relatively narrow major lobe in the directional diagram at frequencies of up to 250 MHz. The light metal frame of the IDA Directional Loop Antenna 1, 3100/11 is crimped to give it stability.

The sensitivity of the IDA Directional Loop Antenna 1, 3100/11 to the magnetic field components appears in the directional diagram as a horizontal figure of eight. The IDA antenna 1 also works when oriented horizontally: Here, the electric field strength has a figure of eight characteristic and the magnetic field a circular one, resulting in a very similar cardioid. 

The Narda IDA Directional Loop Antenna 1, 3100/11 is compatible with the Narda IDA-3106 Interference and Direction Analyzer Base Unit.
