If you have purchased a SteppIR antenna, then you have a controller. There are a few variations, this is the one I purchased for my vertical, with all the options.
Since the first thing I do is take things apart, I figured I might as well photograph it for other curious minds. So, this is not a review, rather a picture tour. I also included links to BETTER connectors then the ones included by SteppIR wich I ended up using.

Front and Back views for those considering it. Note the 25 pin and the 2x9 pin connectors in the back. I do recommend using aftermarket connectors below.

Overall very good construction quality and no issues so far with it. I hope you enjoyed the photo tour.
