      *1 Tester Probe
      *2 Tin Foil
      *3 Antenna Wire

      Check for continuity in the antenna.

      Tech Tips

      Check for continuity at the center of each antenna wire as shown in the illustration.

      Note

      When cleaning the glass, wipe it in the direction of the wire with a soft dry cloth. Take care not to damage the wire. Do not use detergents or glass cleaners with abrasive ingredients. When measuring resistance, wrap a piece of tin foil around the tip of each probe and press the foil against the wire with your finger as shown in the illustration.
