A.H. Systems AK-4G Antenna Kit
GENERAL INFORMATION
INTENDED PURPOSES
This equipment is intended for general laboratory use in a wide variety of industrial
and scientific applications, and designed to be used in the process of generating,
controlling and measuring high levels of electromagnetic Radio Frequency (RF)
energy. It is the responsibility of the user to assure that the device is operated in a
location which will control the radiated energy such that it will not cause injury and
will not violate regulatory levels of electromagnetic interference.
GENERAL DESCRIPTION
The A.H. Systems AK-4G antenna kit series consist of five E-field antennas, one
magnetic loop antenna, and two current probes. Each of the antennas and probes
are provided with calibrations when connected to a 50 ohm input receiver or
spectrum analyzer.
Each of the E-field antennas mount directly to the tripod azimuth and elevation
head. The azimuth and elevation head allows the operator to vary the antenna
azimuth (direction) and to change the antenna polarity (vertical or horizontal).
Cables and an adapter are provided to connect each antenna and probe to either
a BNC or N type connector on the receiver. Cable calibrations are supplied.
To obtain the field strength of the signal being measured, the operator must add
the receiver reading in dBuV, the antenna factor in dB, and the cable attenuation in
dB. This yields the field strength in dBuV/m. Calibrations for the E-field antennas
are supplied at appropriate spacings (1, 3, and 10 meter) to comply with various
specification requirements.
E-FIELD ANTENNAS
SAS-510-4 Log Periodic Antenna 290 MHz - 4000 MHz
The log periodic antenna comes assembled and ready to use.
Operation: Attach the antenna to the tripod azimuth and elevation head through
the screw hole in the antenna base. Connect a cable between the antenna
connector and the receiver. The log periodic beamwidth is 65 degrees and it
should be pointed or aimed in the direction that the received signal is coming from.
SAS-530,542 Broadband Dipole Antenna 160 MHz - 500 MHz
The broadband dipole antenna consists of the SAS-530,542 balun assembly and
two dipole (2" tubular) elements.
Operation: Attach the balun assembly to the tripod through the screw hole in
balun assembly base. Screw the two dipole elements into the 'tee' end of the balun
