GENERAL INFORMATION
t
WARNING
Installation of this product near power lines
is dangerous. For your safety follow the
instructions.
General Descri
p
tion
The HG-52SS is a 52 foot, self-supporting
tower designed to support 9.5 square feet of
antenna area with winds up to 50 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
drainage.

Be sure to check your tower form 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 claim to:
Hy-Gain
308 Industrial Park Road
Starkville, MS 39759
The tower can be extended from its nested
position by manual crank or the use of an
electric motor. A thrust bearing can be bolted
to the to
p
section allowin

a 2" diameter mast.

CHAPTER 2
SAFETY PRECAUTIONS
WARNING
Before you start installation of your tower
let us warn you of the danger of letting any
part of your metal tower system touch
electrical power lines -YOU MAY BE
KILLED!
GeneralSafetyRules
8. Don't climb tower; use separate ladder or
lower tower with gin pole for antenna
rotator servicing.
9. Don't overload. The design load limit is
9.5 square feet of antenna on a two foot
mast for winds u
p
to 50 MPH.
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 than you realize. Someone
falls off a roof or gets electrocuted by
touching a power line with an antenna tower
or metal ladder.
There is no such thin- as a good tower site if it
near electrical power lines. Unfortunately,
iiiost 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!).
DO'S
1. 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
assembl
y
awa
y
from all
p
ower lines.
2. Do install the tower on a calm day and
assure yourself of having plenty of
da
y
li
g
ht to com
p
lete installation.
3. Do stay clear if the tower starts to fall
or come in contact with
p
ower lines.
DON'TS 4. -Do call the power company to remove
fallen towers from power lines or to

4. Don't try to catch the tower if it starts to
fall

6
Don't try to remove any metal objects
from the
p
ower lines.
Don't be afraid to call the power
company for advice when picking a
tower site or removing a fallen tower
froni the power lines.
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 vi~aiq. Do not allow the wire to
touch the victim again. Have someone call the
power company and an ambulance.
7. Don't remove winch handle; use safety
chain with lock to secure_
5. Do crank tower-down to retracted
position when winds are anticipated to
exceed 50 mph.
1. Don't install any tower near power lines.
2. Don't install a tower on a windy day.

Site Selection
The tower requires a concrete base ap-
proximately 42"x 42" x 5'b" 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 l
should allow access to the tower during all
weather conditions.

CHAPTER 3
INSTALLATION PROCEDURES.
Checking Base Foundation Assembly
IMPORTANT:
For proper alignment, the tabs on the tower
base foundation assembly must correspond
with the tabs on the tower_
During shipment or while in storage, damage
may have resulted to the tabs on the tower
base foundation assembly_
Before installation of this tower, check
proper alignment of the tabs. To do this, set
the tower horizontally ou two supports. Attach
the base foundation assembly to the tower
using the 3/4" hardware, as shown below.
If the tabs on the base foundation assembly
are out of alignment, use a large hammer to
realign.

Planning Your Procedure t,
Good planning is a key to a successful and safe
tower installation_ If you're not sure about a..
careful, safe installation, do not try to do it your-
self. Call for professional help (Yellow Pages
under Towers or
y
our local
p
ower com
p
an
y)
.
The tower should be as close as possible
to.its related equipment. Determine the best
possible site while thinking about power lines,
but also think about overhanging tree limbs that
may be blown into the tower during high
winds.
Foundation
Dig a hole 42" square by 5'6" deep, as shown
in Fi

Wood Forms
Construct a wooden frame around the hole to
support the base assembly as shown in Figure
5.
A sample would be the 2"x4", which after
being dried and planed will measure 1 1/2" x 3
1/2" (3.81 x 8.89 cm), or a 2"x 6", which will
measure 1,1/2"x S 1/2"
(
3.81 x 13.97 cm
)
.
In the U.S.A, the dimensions of lumber are
listed, and referred to, as the size after is
roughcut at the sawmill; prior to being dried
p
laned and sold on the market.
Figure 5 Constructing Frame for
Concrete Base
Orient your tower base in the direction your
tower will be raised. The two parallel ears of
the base assembl
y
will be the hin
g
ed side.
Check and realign the tabs, using a large ham-
mer, so they will agree with the dimensions

ASSEMBLY MUST MATCH THE SPACING
DIMENSIONS CALLED OUT IN FIGURE 6.
Drill a 3/4" hole in each cross member in line
with the lower holes in the base assembly as
shown in Fi
