Common questions
How do I restore my purchase?

How do I switch between metric and feet?

How do I change the ITU region?
Open Settings and pick Region 1, 2 or 3 under ITU Region. The Bands screen has the same menu.
How accurate are the lengths?
They are starting lengths. Cut long, then trim with an antenna analyser. Height, ground and nearby objects move the resonance. Always follow your national licence.
