Universal Mount - For attic installations
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. 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.

Chimney Mount - Mounts on a chimney only
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.
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.
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.
