When measuring inside buildings, the field strengths are often very low. For
example, a modern, coated glass window can attenuate a signal at 24 GHz by
about 30 dB. To be able to detect a field strength of such a low level, a high gain
antenna is needed. In turn high gain antennas have a high directivity due to their
design. The LNB antenna 3591/01 is a directive antenna with high gain.
In addition, the directional characteristic can be used to detect the field
strength of geographically separated base stations. Depending on how the
antenna is held, it receives primarily horizontally or vertically polarized RF
signals. A label on the antenna indicates the polarization.

For EMF measurements, national and international standard recommenda -
tions require EMF measurements to be performed isotropically. However,
isotropic antennas are not available for the FR2 frequency range.
The LNB antenna 3591/02 offers an omnidirectional characteristic that
roughly corresponds to the shape of a donut, which is as close as you get to
an isotropic characteristic in the FR2 frequency range. Ideal results with the
3591/02 antenna are therefore obtained in an X-Y spatial plane. To cover all
three spatial axes for isotropic measurements, the antenna must be moved
accordingly during the measurement.
NOTE:
To move the antenna easily, the antenna must be connected to the basic
unit via an extension cable.
 The omnidirectional LNB antenna has its minimum in axial direction
(donut shape antenna pattern). Therefore, do not align the antenna
axially with the RF source during the measurement, as this will create
significantly underestimated results!
