HG915G Installation Instructions

HG915G Installation Instructions
IMPORTANT SAFETY PRECAUTIONS:
LIVES MAY BE AT RISK! Carefully observe these instructions and any special instructions that are included with
the equipment you are installing.
IMPORTANT: Look over the site before beginning any installation, and anticipate possible hazards, especially these:
CONTACTING POWER LINES CAN BE LETHAL. Make sure no power
lines are anywhere where possible contact can be made. Antennas, masts,
towers, guy wires or cables may lean or fall and contact these lines. People
may be injured or killed if they are touching or holding any part of equipment
when it contacts electric lines. Make sure there is NO possibility that equipment
or personnel can come in contact directly or indirectly with power lines.
Assume all overhead lines are power lines.
The horizontal distance from a tower, mast or antenna to the nearest power line should be at least twice the total
length of the mast/antenna combination. This will ensure that the mast will not contact power if it falls either during
installation or later.
TO AVOID FALLING, USE SAFE PROCEDURES WHEN WORKING AT HEIGHTS ABOVE GROUND.
• Select equipment locations that will allow safe, simple equipment installation.
• Don’t work alone. A friend or co-worker can save your life if an accident happens.
• Use approved non-conducting ladders and other safety equipment. Make sure all equipment is in good repair.
• If a tower or mast begins falling, don’t attempt to catch it. Stand back and let it fall.
• If anything such as a wire or mast does come in contact with a power line, DON’T TOUCH IT OR ATTEMPT TO
MOVE IT. Instead, save your life by calling the power company.
• Don’t attempt to erect antennas or towers on windy days.
MAKE SURE ALL TOWERS AND MASTS ARE SECURELY GROUNDED, AND ELECTRICAL CABLES
CONNECTED TO ANTENNAS HAVE LIGHTNING ARRESTORS. This will help prevent fire damage or
human injury in case of lightning, static build-up, or short circuit within equipment connected to the antenna.
• The base of the antenna mast or tower must be connected directly to the building protective ground or to one or
more approved grounding rods, using 1 OAWG ground wire and corrosion-resistant connectors.
• Refer to the National Electrical Code for grounding details.
• Lightning arrestors for antenna feed coaxial cables are available.
IF A PERSON COMES IN CONTACT WITH ELECTRICAL POWER, AND CANNOT MOVE:
• DON’T TOUCH THAT PERSON, OR YOU MAY BE ELECTROCUTED.
• Use a non-conductive dry board, stick or rope to push or drag them so they no longer are in contact with electrical
power.
• Once they are no longer contacting electrical power, administer CPR if you are certified, and make sure that
emergency medical aid has been requested.

Position the "L" Bracket to the back of the Grid
Assembly, noting the orientation required for the
desired polarity.
Determine the polarity which will be chosen for the antenna
installation. The antenna can be installed either vertically or
horizontally polarized.
Position the Feedhorn to the front of the Grid
Assembly, again noting the orientation required for
the desired polarity.
The two polarities are illustrated below:
