The most potent single tower antenna systems ever seen in Amateur Radio

An Innovative Approach to an Age Old Problem

At SteppIR, we value innovation and technical experimentation over just about everything else (except customer service!). Over the years we have innovated, but nothing beats the first original insight we had into how to deliver a fundamentally better antenna. Historically, most multi-band antennas use traps, log cells or interlaced elements as an approach to cover several frequency bands. All of these methods have one thing in common: they significantly compromise performance. The SteppIR antenna system was our answer to this fundamental problem.


SteppIR  Antenna Design

Resonant antennas must be made a specific length to operate optimally on a given frequency. Instead of trying to “trick” the antenna into thinking it is a different length, or simply adding more elements that may destructively interact, our approach is to simply change the antenna length.  With this approach, SteppIR antennas gain optimal performance on all frequencies with a lightweight, compact antenna.  And since the SteppIR can control the element lengths, a long boom is not needed to achieve near optimum gain and front-to-back ratios on every frequency between 40 meters and 10 meters.

Copper tape drwgEach antenna element consists of two spools of flat copper-beryllium tape conductor mounted in the element housing unit.  The copper-beryllium tape is perforated to allow a stepper motor to drive them simultaneously with sprockets.  Stepper motors are well known for their ability to index very accurately, thus giving very precise control of each element length.  In addition, the motors are brushless and provide an extremely long service life.  The copper-beryllium tape is driven out into a hollow fiberglass elements support tube (see below), forming an element of any desired length up to the limit of each specific antenna model (a vertical antenna uses only one side).  The fiberglass elements support tubes (poles) are telescoping, lightweight and very durable.  When fully collapsed, each one measures approximately 59” in length.  Depending on the model, there may be additional extensions added to increase the overall element length. The ability to completely retract the copper-beryllium antenna elements, coupled with the collapsible fiberglass poles makes the entire system easy to disassemble and transport.

Principal of design

The antenna is connected to a microprocessor-based controller (via a 22-gauge conductor cable) that offers numerous functions, including dedicated buttons for each ham band and continuous frequency selection from 40 meters to 6 meters (depending on the model).  There are also 17 ham and 6 non-ham band memories, within which you can select a 180° direction reversal* or bi-directional* mode and it will adjust in approximately three seconds.

Price Increase and other NewsCheckout our new layaway program!

Effective January 1, 2023 we will be raising prices 10% on our entire product line to help mitigate the losses we have suffered from these pricing issues. We are hopeful at some point the parts issues will reach a peak and possibly prices can even go back down again, but so far we are not seeing this happen. We are announcing this price increase now in hopes of giving our customers as much advance warning as possible.

Other news at SteppIR:

In the last year we have made significant changes to enhance our product design, to create what we believe is the most reliable product we have offered in our 21 year history.

Many of you know the struggles we have had with sourcing electronic parts for our controllers, and that is coming to an end - we currently have all the parts required to make controllers, and within a week or two we should  be returning to normal on controller deliveries.

We continue to work on our digital platform, so that we can be in much better contact with our customers - look for us on Facebook, Twitter and Instagram with more to follow under our new slogan/hashtag S9PLUS20.

Look for new programs such as our winter layaway program, for those folks that want to purchase a SteppIR, but can't rationalize a significant payment up-front.

Thanks again for all your support - we appreciate our past customers and look forward to welcoming many more customers now and into the future!
