The Com-Power AL-130R is an Active Loop Antenna (loop size: 19? x
19? [0.5 m x 0.5 m] with electrostatic shield), operating
over the frequency range of 9 kHz to 30 MHz. It has a
built-in, low-noise preamplifier, which increases overall
measurement sensitivity as well as the overall signal to
The antenna is battery powered (rechargeable 6V NimH
battery pack). The AL-130R can also be powered by
the supplied charger/power adapter. The front panel
has LED indicators for RF ON/OFF, power, battery low,
amplifier saturation, as well as charging status.
The AL-130R is designed for durability, making it the
ideal choice for daily use in most environments. It is
constructed using high grade aluminum, which is also
powder coated for additional durability.
The AL-130R has a 1/4 inch x 20 threaded hole on the
bottom of the preamplifier enclosure, which is used to
secure the antenna to any tripod or antenna mast with a
compatible mounting arrangement.
support for this antenna. Using this tripod, the centerpoint
of the loop can be adjusted from 0.95 meter to
1.35 meters (37? to 53?).
The antenna is individually calibrated using NIST
Traceable equipment per IEEE 291. The calibration
data, along with certificate, are provided.
The AL-130R Active Loop Antenna is intended for use
as an EMI test antenna for qualification-level regulatory
compliance measurements per most commercial
product test procedures including, but not limited to,
ANSI C63.4, along with most CISPR, EN, ETSI standards.
Typically, the antenna is positioned vertically with the
center-point of the loop elevated one meter above the
ground. The loop is then rotated about its horizontal
and vertical axis to achieve the maximum reading at
The AL-130R can be used for Electric field (E-Field) or
magnetic field (H-Field) measurements. Factors are
provided for both types of measurements.
Remote Operation (Optional)
As per ANSI C63.4-2014, the use of an active loop
antenna for compliance testing is permitted in a nonsheilded
environment ONLY if the saturation indicator
is continuously monitored during the course of testing.
comes in very handy for this application.
The RAI-100 is a compact controller which is used to
enable/disable the RF measurement circuit and monitor
saturation and battery low indicators remotely via a
fiber optic cable up to 30 mtrs in length
