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.  
8.Remove the nut and washer from the top of the last elem  
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.

General Installation Instructions  
for Mast Mounted Antennas  
Where To Install Your Antenna  
1. Assemble your antenna on the ground at the installation site  
per the instructions.  
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:  
2. On the ground, attach the antenna to the mast. Pull enough  
coax downlead and connect to the antenna per its instructions.  
3. To insure that the mast does not fall, a durable nonconductive  
rope should be attached to each ten foot section as it is raised.  
4. Install the selected mounting bracket.  
1. Measure the length of your antenna and multiply by 2.  
2. Add this measurement to the length of your tower/mast.  
5. If you are using guy wire installation (not included) instead of  
a mounting bracket:  
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.  
• Install guy anchor bolts.  
• Estimate length of guy wire and cut.  
• Attach to mast using a guy ring.  
6. Carefully take the antenna and mast assembly to the mounting  
bracket and insert. Tighten the clamp bolts. In case of a guyed  
installation, it will be necessary to have at least a second  
person hold the mast upright while the guy wires are attached  
and tightened to the anchor bolts.  
NOTES:  
• Remember when doing any installation, keep the  
mast plumb.  
Antenna Removal  
Removal of the antenna should be exactly the reverse of the  
installation instructions. Please, for your own safety, follow  
the instructions for installing the antenna starting with the last  
step first.  
• 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 manufacturer’s instructions carefully.  
House Construction Obstacles:  
For homes made of stucco, clad with aluminum siding or that have  
internal foil paper insulation, the antenna must be installed on the  
side of the house that faces the broadcasting tower. These  
materials may prevent signals from going through it.

(continued)  
Chimney Mount - Mounts on a chimney only  
Universal Mount - For attic installations  
Fig. 12  
Suggested height limitation: 10 feet above chimney top.  
The chimney is often an easy and convenient mounting place,  
but the chimney must be strong enough to support the  
antenna in high winds. Do not use a chimney that has loose  
bricks or mortar. A good chimney mount consists of a 5 or 10  
foot 1-1/4” diameter steel mast and two heavy duty strap  
clamp-type brackets.  
An attic installation is the easiest, fastest and most convenient  
type of antenna installation, especially if you do not have easy or  
secure access to an outdoor area. Attic installations work best in  
areas where strong signals are present. Roofing materials,  
aluminum foil on insulation, aluminum or steel siding, metal  
gutters at the attic level, and metal lath under old plaster walls  
all can interfere with reception. Use the universal mount to  
secure the mast and antenna to a rafter.  
1. Insert the threaded end of the strap hook, (the one secured to  
the strap) through the end portion of the “Z” mount (hole A).  
Take one of the loose strap hooks and insert into hole B.  
NOTE: It is important to thread the nut only 1/4” onto the hook, so  
that it may later be tightened to take out the slack and make the  
strap secure to the chimney.  
1. Screw the universal mount into a supported rafter or beam.  
2. Using the U-bolt, bracket and nuts, secure the mast to the  
universal mount.  
3. After you align the mast perpendicular to the floor, tighten  
the nuts securely.  
2. Go around the chimney with the strap; slip the strap clip onto  
the strap, and then secure the other end of the strap by inserting  
the strap into the strap hook that is in hole B. The strap clip is  
used as follows: (See figure 12.)  
a. Slide the strap through the loop section of the clip and bend it  
around through the upright section of clip.  
b. Bend the upright sections of the clip down with pliers,  
pinching the strap firmly.  
3. At this time, remove any slack in the strap by tightening the nuts  
at holes A and B.  
4. Repeat the above steps to secure the lower mount to chimney.  
(It is recommended that the mounts be a minimum of 18” apart.)  
NOTE: Install the upper bracket just below the top course of  
bricks, and the lower bracket two or three feet below the upper  
bracket. For maximum strength, space the brackets as far apart  
as possible.

5. Place the mast against the mount and secure it in place using  
the mast support clamps and nuts.

Grounding  
(continued)  
NOTE: Grounding the antenna and mast provides lightning protection for  
the antenna and your TV set.  
Wall Mount  
All outdoor antenna installations should be properly grounded. To  
effectively protect the installation, the coaxial cable(s) should be grounded  
before they enter the house. The grounding of the coaxial cable is made  
using a “ground block” and copper wire (not supplied). For information and  
the materials needed to ground your antenna installation, visit your local  
electronics store.  
If you are not sure how to install the grounding block and rod, please  
consult your local retailer or TERK’S Technical Support Department at  
1-800-942-8375.  
Suggested height limitation: 10 feet above the rooftop.  
An outside wall of your home is also an easy and convenient  
mounting place, but the wall and fasteners that you use must be  
strong enough to support the antenna in high winds. Ensure that  
the brackets are securely fastened to a solid part of your wall.

Example of antenna grounding as per  
National Electrical Code, ANSI/NFPA 70  
1. Space the mounting brackets on an exterior wall – be sure  
to clear roof eaves or any other obstacles.  
2. Secure the brackets to the wall using the 4 lag screws.  
3. Insert the mast between the saddles and secure with the  
nuts and bolts.

Tripod Mount (not included) - Used on peaked and flat roofs  
Suggested height limitation: 10 feet above the rooftop.  
Installation involving a tripod mount and a mast should be guyed if  
the mast is ten feet or more. The tripod mount must be securely  
anchored to the roof as should the guy wires. Apply roofing  
compound around the base of the brackets, screws and eyebolts to  
weather proof the holes in the roof. Try to lag bolt the legs to the  
roof rafters. If not, install wood plates in the attic and install bolts  
to secure the mount.

1. Mount the 75 ohm grounding block or discharge unit as close as possible  
to where the downlead enters the house.  
2. The ground wires for both the mast and the downlead should be copper  
or aluminum wire, number eight (8) or larger.  
3. The downlead wire from the antenna to the antenna grounding block or  
discharge unit and the mast ground wire should be secured to the house  
with stand-off insulators, spaced from four (4) to six (6) feet apart.  
Telescopic Mast (not included)  
The minimum safe diameter of the mast is 1-1/4 inches for this  
type of mount. Guy wires should be equally spaced in at least three  
directions. Use at least three guy wires for each ten foot section  
of mast. Make sure guy wires are spaced evenly apart.  
NOTE: In the case of a “ground up” antenna installation, it may not be  
necessary to ground the mast if the mast extends four or more feet into the  
ground. Consult a TV serviceman for the proper depth in your location.
