■ Outdoor Antenna Grounding:
● If an outside antenna is connected to the receiver, be sure the
antenna system is grounded so as to provide some protection
against voltage surges and built up static charges.

No. 70-1984, provides information with respect to proper
grounding of the mast and supporting structure, grounding of the
lead-in wire to an antenna discharge unit, size of grounding
connectors, location of antenna-discharge unit, connection
grounding electrodes, and requirements for the grounding
electrode.
■ Object and Liquid Entry:
Care should be taken so that objects do not fall and liquids are not
spilled into the enclosure through openings.
