The process should give us a better understanding of what goes on in the complex world of transmission lines.
+    * Smoke or No Smoke: To improve the efficiency of a magnetic loop antenna the diameter of the tubbing use to make the loop is doubled. The capacitor for the original antenna was just adequate. Smoke or no smoke?
