General Installation Instructions for Mast Mounted Antennas
Caution
For outside installations, make sure you do not mount the antenna upside down or block the bottom of
the antenna at the cable exit. The correct mounting position is with the cable pointing down (towards the
ground) so that any moisture will drain through the antenna drain holes. The antenna ships with a yellow
mounting instruction label temporarily attached to the antenna radome.
The following instructions are common to most mast mounted installations.

Assemble your new antenna on the ground at the installation site.
Attach the antenna to the mast and connect its coaxial cable while you are on the ground.
Make sure the mast doesn't fall the "wrong way" should you lose control as you raise or take down
the mast. Use a durable non-conductive rope secured at each two foot level as the mast is raised.
Have an assistant tend the rope, ready to pull the mast clear of any hazards (such as power lines)
should it begin to fall.
Use the mounting bracket provided with the antenna.
If the installation will use guy wires:
Install guy anchor bolts.
a.
Estimate the length of guy wire and cut it before raising the mast.
b.
Attach guy wires to a mast using guy rings.
c.
Carefully connect the antenna and mast assembly to its mounting bracket and tighten the clamp
bolts.
In the case of a a guyed installation, you must have at least one assistant to hold the mast upright
a.
while the guy wires are attached and tightened to the anchor bolts.
Attach the provided self-adhering "DANGER" label at eye level on the mast.
Install ground rods to remove any static electricity buildup and connect a ground wire to the mast
and ground rod. Use ground rods designed for that purpose, not a spare piece of pipe.
Use No. 10 AWG copper or No. 8 or larger copper-clad steel or bronze wire as ground wires for both
mast and lead-in. Securely clamp the wire to the bottom of the mast.
Secure the lead-in wire to a lightning arrestor and mast ground wire to the building with stand-off
insulators spaced from 4 feet (1.2 meters) to 8 feet (1.8 meters) apart.
Mount the lightning arrestor as close as possible to where the lead-in wire enters the building.
Drill a hole in the building's wall as close as possible to the equipment to which you will connect
the lead-in cable.
