3. Mount the antenna on a mast or tower that is well grounded to earth.

interferes with the grounding connection.
5. Connect all power and antenna grounds to a common single point
such as an equipment rack, cabinet enclosure chassis, or antenna
tower. Connect this single-point ground to a solid ground connection
to earth.
6. Install a lightning arrestor where the antenna cable enters the building
or cabinet. Ground the lightning arrestor to a single point chassis
ground. Follow the instructions provided by the manufacturer.
2.6.6 Weatherproofing
Good weatherproofing is the key to antennas that work well in all weather
conditions. If water or moisture enters a cable or connector, it
significantly reduces signal levels and often ruins the cable and/or
connectors.
All connections that may be exposed to outdoor weather conditions or
moisture, including condensation must be weatherproofed.
NOTE: Whenever possible, connect and weatherproof the cables,
antennas, and any accessories on the ground. Minimize the amount of
work performed on a roof or a ladder.
