2 Safety Instructions
B Warning
Installation of this product near power lines
is dangerous. For your safety, keep ladder and
antenna away from power lines.
Contact may cause electrocution.
2.1 Antenna Grounding and Safety
Warning
1
Outdoor antennas and lead-in conductors
from antenna to a building, should not cross
over open conductors of electric light of
power circuits. They should be kept away
from all circuits to avoid the possibility of
accidental contact.
2
Each conductor of a lead-in from an
outdoor antenna should be connected with
an antenna discharge unit. Antenna discharge
units (or Lightning Arrestors) should be
located outside the building or inside the
building between the point of entrance
of the lead-in and the TV, and as near as
practical to the entrance of the conductors
to the building.
2.2 About the Design of Your Antenna
The design process of this antenna began in the
very early days of DTV transmission, largely
because of frustration with the selection of
antennas on the market. The old antennas
were all legacy technology from the 1950s.
Popular thinking of the early days of DTV
transmitting was “radio waves have not changed
so why should we use different antennas for
DTV?” Radio waves have not changed but
our transmission system and performance
expectations have. We designed this antenna
to be an integral part of the DTV transmission
and reception chain. It is designed to maximize
the strengths and minimize the weakness of
the new ATSC system. It was designed to work
with the DTV tuner and capture a more stable
signal so the DTV tuner can do its job with a
minimum of effort and create a razor sharp and
stable picture on your DTV. This antenna was
not designed by simulated theoretical physics;
it was designed to work with the physics of the
real world, the real world of changing weather,
cities and mountains. This antenna will work in
areas where others completely fail or provide
marginal results with part time reception.
D Note
For final installation and connection of your
antenna, additional hardware may be required.
Before starting assembly, please read through
the instructions carefully to determine your
specific requirements.
