• Antenna Installation - When installing an outside antenna
system, extreme care should be taken to keep from touching
such power lines or circuits, as contact with them may be fatal.
• Note to CATV System Installer - This reminder is provided to
call the CATV systems installer’s attention to Section 820-40 of
the NEC, which provides guidelines for proper grounding and, in
particular, specifies that the cable ground shall be connected to
the grounding system of the building, as close to the point of
cable entry as practical.
