Safety Precautions
(continued)
Follow These Rules and Live:
1. Perform as much antenna assembly on the ground
as possible.
2. Watch out for overhead power lines and be sure to select an
antenna site well away from all overhead wires. Check the
distance to the power lines before you start installing. It is
recommended that you stay a minimum of twice the length
of the antenna plus the length of the mast away from ALL
power lines.
3. Do not use a metal ladder.
4. Remember, even the slightest touch of the antenna to a
power line can cause a fatal shock. Do not try to guess
which overhead wires carry high voltage - check with the
power company.
5. Never install the antenna outdoors at night, when it is windy,
or during rain or snow.
6. Have a spotter when you are on the roof; they can see things
you may miss.
7. If you start to drop the antenna, let it go. You could lose your
balance and fall also.
8. If anything comes into contact with a power line - CALL YOUR
POWER COMPANY! DO NOT ATTEMPT TO REMOVE IT
YOURSELF! They will remove it for you.
9. Mast, downlead and guy wires are all excellent conductors.
Keep them away from power lines also. Do not run the
downlead cable over power wires.
10. Make sure the antenna installation is secure.
11. Do not stand on, lean on, hang from or hang anything on the
antenna once it is mounted.
12. Make sure the antenna mast assembly and downlead are
grounded per National Electrical Code.
(See page 14.)
Lightning Protection and Grounding:
Always plug your TV and other electronic devices into a
quality surge protector (such as the TERK TSP-6), for
maximum protection against lightning and power surges.
Do not run the downlead cable over power wires.
Make sure the antenna downlead is connected to suitable
lightning arrestors.

Safety Precautions
WARNING
READ ALL OF THE ATTACHED SAFETY INSTRUCTIONS BEFORE
PROCEEDING WITH ANTENNA AND/OR MAST ASSEMBLY AND
INSTALLATION. INSTALLATION OF THIS ANTENNA NEAR
POWER LINES IS DANGEROUS. FOR YOUR SAFETY, FOLLOW THE
INSTALLATION INSTRUCTIONS.
Use extreme caution when installing or removing an outdoor
antenna that is located close to overhead wires such as power
lines, telephone lines or cable TV lines. If any part of the antenna
makes contact with overhead power lines, touching the antenna
or the antenna cable can cause electrocution and death. If the
antenna is in contact with any type of overhead wires, call your
power company and ask them to send a qualified technician to
remove the antenna. Do not attempt to remove it yourself.
Important Safety Precautions:
Many do-it-yourself and professional antenna installers are
injured or killed each year by electric shock. While anyone can
see the obvious danger of falling, the most resourceful
sometimes fail to recognize overhead wires as being potentially
lethal. To touch any part of the antenna to these overhead wires
is the same as touching the wires with your bare hand. A very
serious shock is almost sure to result when contacting an
electrical wire, and in the case of primary wires on the top of
poles, the shock is like being struck by a bolt of lightning. Many
power wires are within 20 to 25 feet of the ground and could
easily be touched by an assembled antenna.
If you are not completely sure that you can install the antenna
safely, Do Not Try It! Contact a professional installer instead.

1. Unfold the elements on the two reflector booms until they lock
into place. Make sure that they are straight and perpendicular to
the boom.
2. Attach the two reflector booms using the attached nut and bolt so
that they are perpendicular to the smaller boom.
(See figure 1.)
3. Unfold the reflector booms until they lock into place.
(See figure 2.)
4. Unfold all the other elements on the antenna until they lock
into place ensuring that they are flat and parallel to each other.
(See figure 3.)

7.Remove the rear nut and bolt from the larger antenna section.
Slide the narrow boom of the rear antenna into the larger
section.Tap lightly with a rubber mallet on the end of the
small boom, aligning the bolt holes.
(See figure 6.)
Re-install the bolt and nut; be sure to tighten it securely.
8.Remove the nut and washer from the top of the last element
holder stud on the top side of the antenna and repeat the
process on the last element holder stud on the bottom side of
the antenna.
(See figure 6.)
Place the phasing lines from the rear
section over the stud, one on the top side, one on the bottom,
and reattach the washers and hex nuts. Tighten them securely.
9. Lay the boom brace on top of the antenna keeping all the
U-bolts on the same side. Locate the bolt hole in the corner
reflector and attach the brace with the bolt and nut. Swing the
boom brace down towards the rear. Form a "V" with the metal
straps. Bolt the V to each side of boom.
(See figures 7 and 8.)

bolt. Slide the narrow boom of the front antenna into the
larger section. Tap lightly with a rubber mallet on the end
of the small boom aligning the bolt holes.
(See figure 4.)
Re-install the bolt and nut; be sure to tighten it securely.
NOTE: Make sure that the side of the small boom with the phasing lines
line up with the nuts on the large boom.
6.Remove the nuts and washers from the top of the first element
holder studs.
(See figure 5.)
Place the phasing lines from the
front section over the studs, and re-attach the washers and
hex nuts. Tighten them securely.

11.Loosen the U-bolt nuts, slide the TV38 antenna over the mast and
lightly tighten the two mast clamps.
(See figure 10, 11.)
The top side of
the antenna is the side with the black plastic pieces on it.
NOTE: The top side of the antenna is the side with the black plastic pieces
on top of the large boom.
12.Connect the coax downlead to your TV. Rotate the TV38 antenna
until you receive the best picture. You will probably need a helper to
view the TV set while you are rotating the antenna.See Pointing
the Antenna Towards the Broadcast Tower
NOTE: Point the small end of the antenna towards the station
broadcast tower.
13.Tighten the two mast clamps securely.
14.Secure the coaxial downlead to the mast (using cable ties) to prevent
it from whipping by the wind.
15.Ground the antenna and mast per the accompanying grounding
instructions.
(See page 14.)

Where To Install Your Antenna
Before attempting to install your antenna, decide on the
best location to install your antenna for both safety and
performance. To determine a safe distance from wires, power
lines and trees:
1. Measure the length of your antenna and multiply by 2.
2. Add this measurement to the length of your tower/mast.
If you are unable to maintain this safe distance, STOP! Get
professional help. Most antennas are supported by tripod
masts or pipe masts attached to the chimney, roof, or to the
side of the house. Generally, the higher the antenna, the better
it performs. Good practice is to install your antenna about 5
to10 feet above the roof line and away from power lines and
other obstructions.
NOTES:
Remember when doing any installation, keep the
mast plumb.
For mast support, use only 1-1/4 O.D. pipe or larger antenna
mast sections. Lengths over 10 feet should be guyed at least
every 10 foot section.
Not all mounting methods are shown here. Read and follow
the mount manufacturers instructions carefully.
