The SAS-510-2 Log Periodic Antenna (also known as a log periodic dipole array) is a
compact, lightweight antenna that has been designed to ensure maximum gain, low
VSWR and high power handling capabilities. This compact design is an ideal solution for
EMC testing where the reduced size of the antenna is preferred to minimize chamber wall
coupling and increasing the half power beamwidth to a more acceptable angle that will
cover the whole device under test. Constructed of lightweight aluminum, the SAS-510-2
Log Periodic Antenna has been manufactured to operate over a very wide bandwidth.
Weighing in at just 1.5 pounds this Log Periodic Antenna is one of the lightest antennas
commercially available.
Assembly: 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 45 degrees and it should be pointed or aimed in
the direction that the horizontal received signal is coming from.
