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!

Gone for Hamvention!We are out of the office for Dayton's annual Hamvention. Come see us at the booth!

Our sales and engineering team are out of the office this week for Dayton's annual Hamvention! We will be answering calls and emails remotely as best as we can and might not be getting back to you until the week of May 23rd.

Controller's are Shipping!

We now have all the parts for the electronic controllers in-house, and we anticipate rapidly catching up to our backlog. This will also have a significant effect towards reducing our lead-times for new orders.

We have had many challenges at SteppIR during these unprecedented times, and we are a very proud company as we emerge stronger than ever - we could not be in the position we are without you, our fantastic customers.

See you at Hamvention!
