Antenna 2 covers the frequency range from 200 MHz to 500 MHz, making it eminently suitable for interference and spurious signal searches on all communications services within this band, and also includes the 433 MHZ ISM frequency.

A dipole antenna with optimized directional characteristics can be used from 200 MHz onwards. It has a much more pronounced directivity compared to the frame antenna. It also provides high sensitivity with an antenna factor of typically 23 dB(1/m) at 300 to 400 MHz.

Similar types of antenna, known by radio hams as HB9CV, have been used since the 1950s. The principle is based on the combination of two Hertzian dipoles, i.e. dipoles that are short compared to the wavelength. The desired directivity is achieved by connecting the two dipoles in opposite phase and selecting suitable dimensions and spacings.

The directional characteristic in the horizontal plane shows a relatively narrow lobe in the main direction and small minor lobes in the opposite direction. The vertical characteristic is a cardioid similar to that of the frame antenna.

  • The handle is ergonomically shaped and fits snugly in the hand, and yet it is a technically sophisticated device with several function. It accepts antennas in horizontal and vertical positions, contains a switchable preamplifier, a compass, position sensors, and a measurement start / stop button. The antenna handle communicates with the basic unit through a control cable.

  • Antenna 1 covers the frequency range from 20 MHz to 250 MHz. It therefore includes the ISM band at 27 MHz, and is particularly suitable for interference and spurious signal searching in the VHF broadcast radio range, but also covers the lower end of VHF television and includes DAB frequencies.

  • The 400 MHz to 6 GHz frequency range of Antenna 3 covers the entire spectrum of mobile communications including LTE and WLAN, and also includes L, S, and C band radar, for example.

  • This low-frequency loop antenna is particularly suitable for detecting defective or poorly screened switched power supplies or electrical controllers that emit interference, and for identifying interference due to power line carrier systems, or demonstrating interference with other signals in the very low frequency range (ultra long wave).
