New HG3 Stepper Mag Loop Available!

June 2, 2020 Aurora, Oregon

The HG3 our flagship magnetic loop antenna, is now available for sale. The HG3  delivers 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. Order the HG3 Stepper Mag Loop here.

HG1 Controller rate range

Update: While not marked on the controller, the usable range of the RATE control is from approximately the 10 o’clock position to the MAX position with the knob CW position indexed at MAX (see the figure at right). Then alternately tap the DOWN and UP buttons for minimum SWR (any SWR under 2.0 is works very well). Also see MLA Instructions Assembly, deployment and tuning.


The HG-1 Remote Loop Tuner
It is a compact, easy-to-use remote tuner for a Magnetic Loop Antenna (MLA). It is designed specifically as a retrofit for the popular preciseRF HG-1 MLA. Now you can place your HG-1 Magnetic Loop at a remote location, such as the top of your RV, away from obstructions, for better radiation efficiency and less interference. The controller features an efficient, low noise, pulse width modulated, motor controller.

PreciseLOOP HG1 Expedition 
The PreciseLOOP antennas are for Receive and Transmit use. The new PreciseLOOP HG-1 is a high gain Magnetic Loop Antenna (MLA). It can be deployed quickly and is ideal for use in places where HOA 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.
