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

Extended Antenna Details

SteppIR Communication Systems offers a wide variety of antenna options.  Our objective is to always have the answers that our customers require, and this section of our website is provided for those that want to have much more detail on each model. Some of the information is redundant as there are similarities between multiple products, but we tailor the information specifically to each product, right down to the part numbers of the accessories for that particular antenna model.  Enjoy, and if you have further questions please don’t hesitate to contact our sales or tech support departments!

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!
