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.
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.

Assembly and installation instructions
Before assembling the antenna, take a moment to familiarize yourself with the
antennas’ construction. Notice that the boom of the antenna has a top and bottom. The horizontal elements are mounted to the top side of the boom. The
reflector on the other hand, does not have a specific top or bottom.
1. Extend the folded drive element by carefully folding the “wings” outward so
they are at 90 degrees to the boom. (fig.3)
2. Attach Transformer to bottom studs of drive elements with wing nuts and
washers. (fig.4)
3. Slide the reflector screen onto the boom from the rear until the screw holes
of the screen bracket line up with the holes on the top and bottom of the
boom.Attach the screen to the boom using two (2) 1-1/2” bolts,lockwashers
and wing nuts.
Tip:
To make it easier to fit when sliding the screen onto the boom, squeeze the top
and bottom of the screen towards each other.
4. Insert end caps at end of boom (fig. 5).
5. Attach the antenna to the mast: Assemble U-bolt to cross piece. Attach U-
bolt assembly loosely to antenna, using saddle, lockwashers and nuts. insert
mast through U-bolt.Tighten nuts securely (fig.5) (Mast sold separately).
6. Connect 2 mast sections as shown in figure 6 (included in SDV9201K only)

7. Connect a good quality RG-6 coaxial cable to the transformer. Slide the
weatherproof boot over the connection firmly until it seals (fig.7) (Cable sold
separately)
8. Attach cable standoff to mast as shown in figure 8 (included in SDV9201K
only)
Aiming the Antenna
Before permanently mounting the antenna for digital television (DTV) reception
it is a good idea to perform a quick sight survey to find the spot with the best
signal. Moving the antenna one way or another just a few feet can make a
tremendous difference in the success of the antenna installation.
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.
Overview
DTV is a little different than analog TV.With analog TV peak signal strength was
the most important factor for good reception and creating a good picture.With
DTV peak signal strength is not the most important factor for good reception.
This means that our old methods for finding a location and aiming a TV antenna
will not give us the best results for DTV. In choosing a permanent location for
our DTV antenna we want to look at a couple of mounting locations.There are
two methods for testing for the best antenna location:
1. Terrestrial Digital receivers internal signal strength indicator.
2. Conventional Analog TV pointing method.
Tip:
Do not use a convention signal strength meter for installing a DTV antenna.
Chances are this will give you false information and cause the antenna not to
work reliably. Severe ghosting is the number one reason for DTV reception
problems. Most severe ghosting occurs in locations where there is plenty of signal strength. A conventional signal strength meter will find this location.
