QST reviews HG3 Stepper Mag Loop!

ARRL Reviewed the HG3 Mag Loop Antenna in the Jan 2021 issue of QST. it gave it high marks for effectiveness, easy of use and precise repeatable operation. See the entire review here: QST HG3 review

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 Expedition on SOTA field day

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.
