Technical Support Resources

SteppIR tests every individual element housing unit (EHU) and every electronic controller, before shipping.  The odds of there being a manufacturing defect as part of a new antenna installation are extremely low – most issues are isolated to customer wiring problems – wiring of a SteppIR is not difficult, but it does take patience and accuracy.  We will always require that a voltage resistance test is conducted as part of any troubleshooting process.  Most issues can be self-solved by using information found on this page, click on the troubleshooting link below for more information.

Troubleshooting Tips

EHU Identification and Selection

This is a great resource for determining the correct EHU for a given antenna, whether you need to order a new one or have issues with an existing EHU
