Description
The Log Periodic antenna Model AL-100 is a broad-
band antenna for use in the 300-1000 MHz frequency
band. This antenna can be used for EMC emissions
measurements and also for immunity testing. The
antenna is constructed with light weight aluminum
with corrosion resistant conductive coating.
Each antenna is individually calibrated. The calibra-
tion data is provided with each antenna to maximize
measurement accuracy. The AL-100 can transmit up
to 50 W of continuous power for transmit applications.
The fi ber glass mounting base allows the antenna to
be mounted in vertical or horizontal polarizations.
The mounting base also has a 1/4 inch x 20 threads.
This enables the antenna to be attached to an antenna
tripod such as model AT-100 tripod.
The AL-100 can also be mounted on an antenna mast.
The antenna has a two year warranty.
Application
The AL-100 Log Periodic antenna is used for emission
and immunity testing to verify compliance for FCC,
CE and MIL-STD 461 specifi cations.
Log Periodic antennas allow quick sweep measure-
ments without a band break. This feature makes it
convenient to use the Log Periodic antenna with a
automated emissions or immunity measurement sys-
tem. The size of the antenna also allows it to be used
in a small area like a shield room.
The Log Periodic antenna was designed to get a smooth
response curve for the antenna factors to minimize
measurement errors.
The calibration data provided with each antenna is
used to calculate fi eld strength measured for the se-
lected frequency. The antenna factor (dB/m) for the
selected frequency is added to the measured output
(dBV) displayed by the EMI meter to obtain fi eld
strength (dBV/m).
