AA6E SteppIR

This site is about the SteppIR antenna system at AA6E.

Aug-Sep 2018

Some "irregularities" have been noted -- high SWR readings, inconsistent tuning, etc. There is a spare EHU (motor-tape assembly) on hand, but which if any elements need replacing?

See the Details!

This 3-element (20 - 6 M) antenna is about 14 years old, and my controller is the original model (no model name!) running firmware 3804.

The tentative conclusion is that one (or more) elements may be "sticking" at maximum extension. Possibly that may be the director. We also see different behavior between the 3 patterns (norm, 180, bi-directional). Unfortunately, without a known-good antenna for comparison, it is not clear how sick this antenna is.
