Antenna Mast

The recommended support mast for the AV-680 is steel water pipe between the sizes of
1-3/4" OD to 2 1/2" OD and with a length that will place the antenna base at a safe
height.

Do not use

thin walled conduit, aluminum tubing, or "TV" mast. The AV-680

is designed to operate at a height of 8 or more feet for proper performance. Placement
on the side of a house or garage at eaves level is acceptable as long as the counterpoise
whips will not be in contact any snow on the roof. Placement above metal roofs is
acceptable if the antenna base is at least 5 feet or more above the metal surface.

Antenna Grounding

Although the AV-680 is designed to operate efficiently without the requirement of an
earth ground, SAFETY GROUNDING must still be provided to protect equipment,
property and persons from the hazards of lightning strikes and other weather related
electrical discharges. In addition the coaxial cable feeding the antenna should have the
shield grounded to eliminate the risk of any indoor equipment failure from allowing
hazardous voltages from appearing indoors and creating a shock hazard. The support
mast should be grounded with a large diameter ground wire.

The AV-680 is DC grounded for static discharge. This is accomplished with a choke
coil in the Matching Unit. This coil could fail under high voltage spikes from a near or
direct lightning strike.

Additional protection can be accomplished by grounding the shield of the coax where
it enters the building to a good earth ground or directly burying the cable in the earth
for several feet before it enters the building. The coaxial cable should be totally
disconnected from the station during threatening weather conditions for maximum
lightning protection.

Antenna Guying

For normal operation up to 65 mph winds, the AV-680 will not require guying. For
extreme locations such as tall building rooftops, a safety guy is recommended. Use
Dacron® rope to guy the center radiator. Attach ropes 14 feet above the antenna
base. Use care not to disturb the radiator stubs.
