• Use No. 10 AWG (5.3 mm
• Secure antenna lead-in and ground wires to house with stand-off insulators spaced
• Mount the antenna discharge unit as close as possible to where lead-in enters
• Use jumper wire not smaller than No. 6 AWG (13.3 mm
• An outside antenna system should not be located in the vicinity of overhead power
circuits, or where it can fall into such power lines or circuits. When installing an outside
antenna system, extreme care should be taken to keep from touching such power lines
or circuits as contact with them might be fatal.
• For added protection for the TV during a lightning storm, or when it is left unattended
and unused for long periods of time, unplug it from the power outlet and disconnect it
from the antenna or cable system. This prevents damage to the TV due to lightning
and power line surges.
