UNPACKING AND UNCRATING
GENERAL DESCRIPTION
This model is a 54-foot self-supporting tower
designed to support 16.0 square feet of antenna
area with winds up to 60 mph. This all steel
tower has a guide system that allows the
tubing to be open at each end insuring
complete galvanizing and total moisture
draina
g
e.
The tower is extended from its nested position
by manual crank. A thrust bearing can be
bolted to the top section allowing a 2"
diameter mast.
Be sure to check your tower for any freight
damage or missing parts. If you find damage,
notify the trucking line that delivered the
equipment immediately and advise Hy-Gain of
the damage. Send a copy of the freight damage

GENERAL SAFETY
Hundreds of people are killed each year
because they don't use common sense when
they install their towers or antennas. It
happens more often then you realize. Someone
falls off of a roof or gets electrocuted by
touching a power line with an antenna tower
or metal ladder.
There is no such thing as a good tower site if it
is near electrical power lines. Unfortunately,
most tower systems, and in many cases, the
ladders used during an installation, are metal.
If any metal tower part or ladder touches a
power line, it completes an electrical path
from the power line through the metal tower
and the installer (YOU!).
Don't overload. The design load limit is
16 square feet of antenna on a 2 foot mast

DO'S
Do install the tower away from power
lines. Check the distance to the power
lines before you start installing - we
recommend you stay a minimum of twice
the maximum length of the tower
assembly away from all power lines.
Do install the tower on a calm day and
assure yourself of having plenty of

Do stay clear if the tower starts to fall or
come in contact with
p
ower lines.
Do call the power company to remove
fallen towers from power lines or to help
pick out a safe antenna site.
Do crank tower down to retracted position
when winds are anticipated to exceed 50
mph.
DON'TS
Don't install any tower near power lines.
Don't install a tower on a windy day.
Don't try to do the job by yourself.
Don't try to catch the tower if it starts to fall.
Don't try to remove any metal objects from
the power lines.
Don't be afraid to call the power company
for advice when picking a tower site or
removing a fallen tower from the power
lines
Don't remove winch handle; use safety
chain with lock to secure.
Don't climb tower, use separate ladder or

If someone is accidentally electrocuted, don't
touch him or the tower if he is still in contact
with the tower or downed power lines. Use a
dry stick, like a broom handle or wooden
ladder, etc. and in one sweep, push the person
free from the tower or knock the wire away
and off the victim. Have someone call an
ambulance and the power company.
SITE SELECTION
The tower requires a concrete base ap-
proximately 42" x 42" x 72" (1067 mm x 1067
mm x 1829 mm) deep. Among the factors to be
evaluated in selecting a tower site are the types
of earth at the installation site and the
nearness of power lines or overhanging tree
limbs. Soil conditions around the tower
foundation should allow access to the tower
during all weather conditions.
Good planning is a key to a successful and safe
tower installation. If you're not sure about a
careful, safe installation, don't try to do it your-
self. Call for professional help (Yellow Pages

Before installation of this tower, check proper
alignment of the tabs. To do this, set the tower
horizontally on two supports. Attach the base
foundation assembly to the tower using the

In the U.S.A. the dimensions of lumber are
listed, and referred to, as the size after it is
rough-cut at the sawmill, prior to being dried,
planed and sold on the market. A sample
would be the two by four (2" x 4"), which
after being dried and planed will measure
11/2" x 3 1/2" (38 x 89 mm), or a two by six
(2" x 6") which will measure 11/2" x 5 1/2"
Orient your tower base in the direction your
tower will be raised. The two parallel ears of
the base foundation assembly will be in the
hinged side.
