HG3 Stepper Mag Loop Available

For Imediate Release

Jun 2, 2020 Aurora, Oregon

The HG3 Stepper MLA, our flagship magnetic loop antenna, is now available for sale. The HG3 MLA 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.

The new HG3 Stepper Mag Loop and companion microprossor based controller

Said Roger Stenbock – W1RMS: “Conceptually, an MLA is a very simple antenna. It is popular because of its performance and simplicity. So it’s no surprise the internet is filled with all types of MLA projects and experiments. Many created by ham radio experimenters. Some are quite elegant, promising impressive capability. Others are notworthy in their simplicity and minimalistic execution. Still others features sophisticated software based solutions.  They all serve the experimenters and home brew market well. My hat off to them. Yet, few, if any, of these projects are available for sale as a ready-to-go product. So many hams built their own MLAs. We listen to them. Many are our customers. They wanted more than the simple loop and touchy tuning cap. They wanted a professional grade, full feature, remotely tuned, no compromise, turn-key MLA.

That’s where the HG3 Stepper Mag Loop comes in.  It is a clean sheet of paper design. The development taking most of last year. Mostly by tackling the myriad of pro and con MLA factors and designing practical solutions. The result is the first turn-key, commercially available, micro controller based, stepper tuned MLA. One that combines auto tuning and rotation into one integrated, high performance package, ready to go on the air immediately.

A special thanks to the development team members: Rob Kirkpatrick KI6HNA – lead tuner design, Travis Cannon – lead firmware design, Audrie Crane-manager manufacturing, Harold Crane – fabrication and Florene Stenbock – word smith”

Price for a complete, turn-key package starts at $935. An introductory upgrade discount offer is available to all current preciseRF MLA customers. Order the HG3 Stepper Mag Loop here.

New Loop Antenna was a big Hit at SEA-PAC ham radio show.

If you attended the Seaside Oregon 2017 SEA-PAC ham radio convention, you may have seen our new products.  Many of you received a demo of our new Precise LOOP Magnetic Loop Antenna (MLA). The interest was intense. As a result, in under twelve hours, we sold out the entire inventory of Loop antennas, tripods, baluns and 80 meter resonators we brought to SEA-PAC. We are now busy replenishing and building another larger production run to fill the demand. We expect the next production quantity to be ready early July, 2017.  The introductory show prices were $399 for the Precise LOOP High Gain model and $299 for the Precise LOOP SOTA model. We will update our website to make them available directly online at the show price for a limited time. In the meantime, check for more information. Mag-loop-data-sheet2.pdf

Roger explaining the loop benefits

Eric Swartz WA6HHQ of Elecraft, using our new Precise Loop antenna

Eric Swartz WA6HHQ of Elecraft, is shown using our new Precise LOOP antenna in his booth. Eric was our very first Loop customer. He was very impressed with our loop and sent a number of customers our way.

Here Roger Stenbock W1RMS, is explaining the unique loop benefits and performance to some of the many hams stopping by our booth. The 45W higher power and 80 Meter option, available on the Precise LOOP High Gain model, was of particular interest to those wishing to operate at field day and HOA limited QTH locations.

The PG50PS was really well received and we sold a number to hams and home brew engineers. We received a lot of interest right away, some inquiries were from as far as Australia. The introductory and show price was $450. As soon as we get back to the office, we will update our website to make it available at the show price for a limited time directly online.  In the meantime, here is some additional information: PG50PS-datasheet2.pdf.
