Product description

TV Antenna Installation

Does an attic antenna need to be grounded ?

No. However, when an indoor antenna cable is longer than 30 feet, some people ground the antenna/mast because it might help reduce static electricity build up which reduces reception.

To protect your house and your TV, your outside antenna system must be properly grounded.

The power unit uses standard house current (110 Vac), some can also get power from a USB connection. The power unit supplies direct current (DC) power to the amplifier through the coax cable center conductor. There can only be cable between the preamp and the power unit, no splitters/combiners or impedance matchers. Coax ground blocks (for lightning and static protection) and cable connectors can be used if they pass DC power (most do).

Antenna Cable

Loop the cable to the antenna around the mast.
Secures the cable and reduces wind movement loosening antenna connection. Allows for a little extra cable near the antenna for repairs, new antenna, etc.
Tie-wrap cable to mast.

Cable Run

Secure cable to siding with insulated cable straps.

Coax Ground Block Cables

Ground block mounted near the home conduit.
Antenna cable connects to ground block.
Home cable connects to ground block.
Drip Loop just before the cable enters the home. (Prevents water from collecting at the home conduit.
Ground Wire (earth ground) connects to / runs through coax ground block)

GROUND WIRE

AWG 10 (#10) or heavier solid copper wire.
Continuous run, no splice connections.
Run as straight as possible.
Can be bare or insulated.
Run inside or outside.

There are 2 methods for grounding antenna and outside cable systems,

Single POINT Ground

Single POINT Ground is specified for all outside antenna's in some local electrical codes, and sometimes preferred for active antenna's (preamp and/or rotor).

Active or Passive Antenna.
2 ground wires: Antenna mast to earth ground.--------Ground block to earth ground.
Some local electrical codes require

Single WIRE Ground

Single WIRE Ground is a littler cleaner installation and common in passive antenna's (no preamp and/or rotor).

Passive Antenna (no preamp or rotor).
1 ground wire: Antenna mast to / through ground block to earth ground.
Cleaner installation.

EARTH GROUND

The National Electrical Code (NEC) specifies the electrical service earth ground be used as the antenna and cable earth ground. The service ground is the electrode conductor ground rod or ground pipe running directly from the power meter into the ground. Some codes allow the power service earth ground be picked-up inside the home from the Breaker / Fuze Panel ground bus bar. The ground block can also be inside but close to the home conduit.

Note, an antenna mast or cable within 5 feet of a swimming pool must be bonded to the pool bounding grid (ground).
