HG3 Mag Loop Antennas

The HG3 Mag Loop Antennas — our flagship magnetic loop antennas — deliver unprecedented capability, performance, and convenience. It employs a proven, accurate and repeatable stepper motor design. Band selection, remote tuning, including optional loop rotation, is controlled by a microcontroller driving a high-resolution stepper motor. An integrated digital SWR bridge allows auto-tuning based on an SWR scan. This ensures compatibility with most radios. Manual tuning uses a convenient rotary encoder knob – no more finicky push buttons. The four-line LCD shows the band selected, SWR, ERP, Cap value, and more.

HG3plus Controller

The HG3plus controller with RapidTune automatically scans each band for the lowest SWR and works with most HF radios.

Magnetic Loop Antenna

A high gain Magnetic Loop Antenna (MLA) is a convenient, lightweight antenna, which can be deployed quickly.


PreciseLOOP Antennas

The PreciseLOOP antennas are high gain Magnetic Loop Antennas (MLA). They can be deployed quickly and are ideal for use in places where size restrictions make full-size wire antennas impossible, or where there is not enough room to erect a conventional antenna. When designed and constructed properly, an MLA can perform as well or even better than a dipole antenna. The PreciseLOOP is compared to a commercial portable dipole antenna.


Test and Measurement Equipment

PreciseRF test and measurement equipment provide superior performance not available on any other competitive product with high accuracy capability demanded by ham radio operators and engineers alike, at a price that’s affordable.
