Description
The Power Log Periodic antenna model ALP-100 is
a broadband antenna for use in the 300-1000 MHz
frequency band.
The ALP-100 antenna can be used for both emissions
and high power immunity testing. For immunity
measurement the ALP-100 can handle up 500 Watts
at the input.This antenna has low VSWR with good
beamwidth patern.
The antenna is mounted from the center using the
attached pivoting fi xture. This fi xture allows quick
polorization changes from vertical to horizontal. In
addition it can be used to mount the antenna to a tripod
or antenna mast.
This antenna is supplied with individual calibration
data at 3 meters per ANSI C63.5 standard. However,
Com-Power can calibrate the antenna to SAE ARP
958 at 1 meter distance at customer request.
Application
The ALP-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).
