The Com-Power AL-130R is an Active Loop Antenna covering a frequency range of 9 kHz to 30 MHz, featuring a 19 inch by 19 inch (0.5 m x 0.5 m) loop with electrostatic shield. The antenna integrates a built-in low-noise preamplifier that increases overall measurement sensitivity and improves the signal-to-noise ratio of the measurement system. Power is supplied by a rechargeable 6V NiMH battery pack, with a supplied charger/power adapter available as an alternative power source. Front panel LED indicators provide at-a-glance status for RF ON/OFF, power, battery low, amplifier saturation, and charging.
The AL-130R is intended for use as an EMI test antenna for qualification-level regulatory compliance measurements per most commercial product test procedures, including ANSI C63.4 along with CISPR, EN, and ETSI standards. In typical use, the antenna is positioned vertically with the center-point of the loop elevated one meter above ground, then rotated about its horizontal and vertical axis to achieve the maximum reading at each frequency. The AL-130R can be used for both Electric field (E-Field) and Magnetic field (H-Field) measurements, with antenna factors provided for both measurement types.
Since 1992, ValueTronics has served regulated industries, EMC compliance laboratories, and product certification programs with verified equipment backed by named accountability — distinct from drop-shippers and pass-through brokers who never physically handle the instruments they list.
