A.H. Systems SAS-512F-4 Log Periodic Antenna
INTRODUCTION
The SAS-512F-4 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-512F-4
Log Periodic Antenna has been manufactured to operate over a very wide bandwidth.
Weighing in at just 2.3 pounds this Log Periodic Antenna is one of the lightest antennas
commercially available.
The SAS-512F-4 Log Periodic Antenna is the standard workhorse of any EMC compliance
test house. The SAS-512F-4 has an excellent Front to back ratio and cross-polarization
properties that is required per CISPR 16-1 that greatly reduces measurement uncertainty.
This Linearly polarized antenna is an ideal solution for radiated emissions and normalized
site attenuation.
