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.

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.

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.

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.
