There are some basic Standard Practices for installing an antenna and cables to get the best signal, and have a durable and as safe as possible installation.
|1 - Antenna Placement|
|Antennas should be mounted|
|•||as high as possible,|
|•||clear line-of-sight to towers.|
|•||Reception / Signal Factors /|
-- Antenna Height Ground Loss
-- Attic and Room Antenna Loss.
|•||Hardware / Antennas.|
|2 - Mast|
TV antenna mast are typically;
• 5 - 6 feet long.
• 1.25 inch outer diameter.
• 18 gauge galvanized steel.
Never connect more than 2 sections.
Some mast are straight tubing. Some mast are angled, commonly called a J mast. Many J mast have built-in mounting hardware that can be adjusted for roof or side structure mounting.
There are various types of mast mounting brackets that come with different stand-off spacing lengths. Use a spacing that ensures the clearance needed.
|Two secured straps with mounting brackets wrapped around a chimney. Do NOT use if chimney exhaust is from a fire place, wood or coal burner, or other excessive heat source.|
|Eave Gable Mount|
|Homes with a roof eave can use an Eave Gable mast mount. It uses 3 mounting points and a cross bar on the side of the home where the roof top peaks.|
|Side Structure Mount|
|The mast is mounted to the side of the home using 1 or 2 mount points. Two mount points have much better wind resistance. Insure the mast stand off spacing clears any obstructions.|
|J Mast / Mount|
|Mast and mounting hardware in a single assembly. Adjustable mount angle to set for side structure or rooftop mounting. Mast diameter is typically 1 inch and 20 inches long. Single point mount.|
Tripod Mast / Mount
|3 - Antenna Pointing Angle|
A smartphone compass app can be used to locate True North to determine antenna pointing angle. When using a magnetic compass account for the difference between True and Magnetic north. See NOAA's Magnetic Declination Website. Note that local conditions could effect magnetic readings. If possible use landmarks to confirm or establish true north.

|4 - Coax Cable Installation|
RG-6 Quad Shield coax cable is the Industry Standard for outside TV cables.

|5 - Ground Wire|
The antenna mast and the coax cable should be grounded by connecting them to the electrical service earth ground. The ground wire should be AWG 10 (Number 10), or heavier, solid copper wire.
A copper (Cu) or bronze Ground Clamp connects the ground wire to the antenna mast. Don't use an aluminum (Al) clamp.
|6 - Antenna Grounding|
There are 2 methods for grounding antennas and outside cable systems, Single POINT and Single WIRE grounding. Single POINT Ground is specified for all outside antennas in some local electrical codes, and sometimes preferred for active antennas (preamp and/or rotor). Single WIRE Ground is a littler cleaner installation and common when using passive antennas (no preamp and/or rotor).
Single POINT Ground
Single WIRE Ground
The antenna and cable ground wire connect to the electrical service earth ground rod. The service ground rod runs directly from the power meter into the ground. A ground clamp or a bonding termination is used to connect the ground wire to the power service ground rod.
An antenna mast or cable within 5 feet of a swimming pool must be bonded to the pool bounding grid (ground).
|7 - Tools & Parts List|
Basic tools needed include a ladder and assorted screwdrivers, wrenches, sockets, and maybe a hammer etc. You will also need a wood and/or concrete drill, and appropriate drill bits and screws.
