Getting Started
Connecting the Antenna
Screw the SMA angle connector of the antenna connection into
the uppermost right socket of the HF analyser. It is sufficient to
tighten the connection with your fingers. (Do not use a wrench or
other tools because over tightening may damage the threads).
Normally, the sources of radiation in the frequency range subject
to measurement are vertically polarised. Therefore, the antenna
should ideally be aligned as shown in the photo below:
Important: Please do not bend or twist either of the antenna
cables.
For a horizontal antenna alignment please do not twist the cable
itself, but turn the whole measurement device into the right direc-
tion. With the help of the LED at the antenna tip you can control
the connection of the antenna cable to the device.
Please do not touch the antenna cable during measurement.
Further notes to the antenna
The SMA connection between the antenna and the meter is the
highest quality industrial HF connection of this size. Furthermore,
the semi-rigid antenna cable implied has excellent parameters for
the frequency range in question. It is designed for several hundred
bending cycles without causing losses to the quality of the meas-
urements. The special implementation of a second "dummy" an-
tenna cable is the subject matter of one of our pending patents,
and compensates the internal weakness of the "simple-log-per-
antenna" which is based on conductor plates. These are also
sensitive to frequencies below the specified bandwidth, thus pos-
sibly falsifying measurements in the principal direction. The an-
tenna supplied with the meter can suppress these disturbances
by approx. 15 to 20 dB (in addition to the 40 dB of the internal
high pass filter).
