Key facts

Rohde & Schwarz is the world's first manufacturer to develop a DF antenna with compact dimensions that contains both vertically and horizontally polarized antenna elements.

In the free space between the nine vertically polarized dipole anntenna elements, an additional nine horizontally polarized loop antennas have been inserted, which are selected with switches. These loop antennas are significantly more complex than simple wire loops and have been extensively optimized. In conjunction with the tried-and-tested correlative interferometer DF method, a performance is achieved that exceeds all expectations and is nearly identical for both types of polarization.

The R&S®ADD197 is suitable for both stationary and mobile applications and covers the 20 MHz to 1.3 GHz frequency range (horizontal polarization: 40 MHz to 1.3 GHz).

The R&S®ADD197 can be mounted on a vehicle roof by using the R&S®AP502Z1 vehicle adapter. For installation on a mast, the R&S®ADD150A mast adapter is recommended.

For installation heights of more than 30 meters above ground (masts higher than 30 meters, high buildings, mountain tops, etc.), the R&S®ADD-LP supplemental lightning protection is recommended.
