Chapter 3
installing the Antenna
This chapter provides instructions for insTalling, aiming and
grounding the antenna.
The sections covered in this chapter are:
□ Installing the Mast or a Pole
□ Installing the Antenna
□ Installing the Cables
□ Aiming the Antenna
□ Grounding the Antenna and Cables
Installing the Mast or a Pole
This section contains four different sets of installation instructions.
Choose and follow one set, depending on the type of surface on
which you install the antenna:
□ Metal Pole
□ Wooden Surface
□ Brick Surface
□ Cinder Block Surface
Metal Pole
The antenna can be mounted directly onto a metal pole in your
yard. The metal pole should be installed in soil conditions that
provide a firm foundation. Do not install a metal pole if your soil
contains:
□ Many rocks, which prevent you from digging a hole.
□ Excess moisture, which prevents concrete from curing properly.
Notes
• The antenna can be mounted on an existing metal pole which meets
the installation and material specifications listed in this chapter.
• You do not need the mast provided with the antenna for this
installation. However, you should store the mast in case you decide
to relocate the antenna at a later date.
Tools and materials needed for this installation:
1 brick
2 bags ready-mix cement
Container to mix cement
Guy wires/wooden stakes
Hacksaw
Level
Metal pole (6' long min. x
1 '/ 4 " - 1 '/ 2 " galvanized steel pipe)
Shovel
> Warning
• Do not install the antenna near power lines.
> Caution
• Avoid.underground electric, telephone, gas, water and sewer lines
when digging in your yard. Contact your local utility companies for
help locating underground utility lines.
• Do not install the antenna where it could be bumped or jarred by
people, furniture, doors or pets.
• Do not attempt any installation in rainy or windy conditions.
Installation instructions:
1
Dig a hole at least 8" in diameter and 36" deep.
Note
• Bury the pole 6" below the frost line if you live in an area that
experiences freezing temperatures.
2
3
Cut the bottom of the pole at a 45° angle with a hacksaw.
This prevents the pole from rotating after installation.
Place a stone or brick at the bottom of the hole. The 45° cut
on the bottom of the pole should sit on top of the stone or
brick. This allows the cement to cover the angled cut.
. Metal Pole
4
Mix ready-mix cement and pour it into the hole.
Notes
• Stop pouring the cement three inches below the top of the hole if you
intend to cover the cement with dirt or replant grass after the cement
has dried.
• The pole must be vertically level to aim the antenna properly.
5
Hold the pole upright and level it with a bubble level. Place
the level along the side of the pole and take at least two
readings 90° (at right angles) from each other.
