10. Grounding or Polarization - This video product is equipped |
with either a three prong plug for 110 VAC use or a two prong |
flat blade 220 volt type plug. Each type is to be inserted into |

b.Secure antenna
with standoff insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart.
c.Mount antenna discharge unit as close as possible to where
d.A driven rod may be used as the grounding electrode where other types of electrode systems do not exist. Refer to the National Electrical Code, ANSI/NFPA
e.Use jumper wire not smaller than No.6 AWG (13.3mm) copper or equivalent, when a separate antenna grounding electrode is used.
