NOTE Skill and experience are required to install antennas on roofs or other elevated
locations. Make sure to consult your dealer concerning installation.
The JEITA Digital Hi-Vision mark (DH mark) is conferred by the Japan Electronics and Information Technology Industries Association to indiacate the superior
performance of antennas and equipment for both satellite and terrestrial digital TV broadcasting.
Antenna Installation Precautions
¡Be very careful to install antenna at the safest spot possible, so
that parts of the antenna will not cause injury or property damage if
they fall.
¡To prevent electric shock accidents, install the antenna as far away
as possible from wires (powerlines, high voltage wires, telephone
lines) so that it will not come into contact with the wires even if it
falls.
¡Never attempt installation on rainy or windy days. Be extremely
careful also when working under a scorching sun in summer, as
the roof can become very hot.
¡Take necessary safety measures before installing antenna, e.g.
binding the antenna, mounting brackets, and tools to prevent them
from dropping.
¡Working at elevated locations is extremely dangerous. Take all
safety measures possible before installation. When you are on the
roof, you may experience vertigo or experience an exaggerated
sense of height; your feet may become shaky and your footing
unstable. Take special care to avoid slipping.
¡Make sure to remove TV and Tuner AC plugs from AC wall outlets
when you connect 75 coaxial cable from TV and Tuner. If plugs
remain in outlets, electric shock may occur.
¡Do not install the antenna and guy wire by yourself. Make sure that
someone, or preferably two or more people, are present to assist
you.
¡Reception level may differ depending on where you install the TV
antenna. During installation, try to adjust the position, height and
direction of antenna for optimum reception.
¡After typhoon or heavy snow, check the antenna, mounting brackets,
mast, roof mount, and guy wires for any signs of trouble or loosened
bolts and nuts. Replace damaged or bent antenna with a new one. If
you neglect antenna or leave them without proper maintenance,
parts of the antenna and mounting brackets may become damaged
and drop, causing physical injury or property damage.
¡Be careful not to use a rusty or corroded antenna and mounting
bracket. Weak or damaged equipment may loosen and drop,
resulting in physical injury or property damage.

1Turn antenna toward source of UHF signals.
2Check TV screen and fix antenna and mast firmly in direction from which best reception is obtained.
For digital broadcasting, turn the antenna so that Antenna Level value displayed on the Antenna Setting Screen
is at maximum value.
Refer to ‘FOR RECEIVING HORIZONTAL POLARIZATION’ on page 2 for guidance on how to assemble parts other than the mast fixing clamp.

MASPRO's performance data is obtained with painstaking honesty and is completely reliable.
MASPRO guarantees the accuracy of its performance data.
VSWR is the degree of matching
impedance.
An antenna with a VSWR of 3 or
lower (the closer to 1 the better) is
excellent.

ACCESSORY
DIRECTIVITY
Directivity is indicated by front-to-back ratio
and beamwidth.
The narrower the beamwidth,
¡The less likely it is that the
antenna will genarate interference
trough reflected signals from the
front, and
¡The higher the actual gain
produced.
Front-to-back ratio is the ratio of the
forward and backward sensitivity in dB.
The larger the front-to-back ratio, the
less likely it is that the antenna will
genarate interference through reflected
signals from the back.
