At some point it&rsquo;s integrity was called into question, it was labeled &ldquo;Check for Loss&rdquo;, and set aside. I took on this task with my handy RigExpert StickPro which made quick work of it once I refreshed my memory of how to use it (beyond simple SWR measurements).</p> <blockquote> <p>When performing feed line measurements, I avoid coiling it to avoid capacitance between turns. It might not matter for TDR measurements, but it can affect SWR measurements.</p>
