  1. Measure the resistance from the coax center conductor to antenna mast. (Ohmmeter probes at points 2 and 7)
  2. Total resistance of center conductor from end to end (Ohmmeter probes at points 2 and 5):
    • RG-58/RG-59 type cable-less than 0.20 ohms
    • RG-62/RG-62M type cable-less than 3.5 ohms
  3. When checking the resistance, cautiously wiggle the lead-in tip and cable. Refer to TESTING FOR INTERMITTENT AND POOR CONNECTIONS .
  4. Replace the antenna and/or lead-in cable when the above readings are not obtained. Refer to Antenna Cable Replacement  for service procedure.
