Antennacraft HD850 - Manual (Page 2)

Using Coaxial Cable
1.
Thread the supplied matching transformer’s spade terminal
ends through the antenna’s strain-relief tab.
2. Slide the spade terminal ends around the antenna’s lead-in
terminals marked CONNECT LEAD-IN HERE. Secure them
with the supplied flat washers and large wing nuts.
3. Screw the cable’s F-connector onto the matching transformer.
Then slip the weatherboot over the connection. Note: If you
use a cable without a weatherboot, cover the connection
with weatherproof tape.
Using Twin-Lead Cable
1.
Split the twin-lead cable for a length of about 3 inches. Then
strip about 1/2 inch of insulation from both leads.
2. Thread the stripped leads through the antenna’s plastic strain-
relief tab. Wrap each lead around one of the antenna’s lead-
in terminals marked CONNECT LEAD-IN HERE, and se-
cure them with the supplied flat washers and large wing nuts.
UNFOLDING THE ANTENNA ELEMENTS
1. Hold each wing boom and turn its elements until they snap
squarely into place (perpendicular to the boom).
2. Press the supplied small end plugs into the ends of the wing
booms.
3. Fold out the wing booms and secure them into position with
the two supplied 1

-inch screws and wing nuts.
4. Hold the main boom’s elements near the pivot points and
pull them away from the boom until they snap into the lock-
ing plastic support insulators. Note: You may wait to unfold
the elements until you get the antenna up on the roof.
Caution: Do not pull the elements near their outer ends or you
could damage them. Once the elements are locked into posi-
tions, do not attempt to unlock them.
ATTACHING TO THE MAST
We recommend you get the help of another person before you
put up the mast or attach your antenna to it. How you set up your
mast depends on your specific installation. Refer to the Con-
sumer Product Safety Commission information on pages 3 and
4 of this manual for recommended methods.
1. Slide the antenna’s mast clamp assemblies over the end of
the mast, with the main boom on top.
2. Tighten the mast clamp assembly’s lock nuts to hold the an-
tenna in place. Do not overtighten the lock nuts. Caution: The
crossover wires must not touch the antenna boom, the mast,
or each other. If necessary, carefully bend the crossover wires
to provide at least 1/2 inch of clearance.
3. Set up the mast, then rotate it so the antenna’s shortest ele-
ments point toward the stations you want to receive.
I f you use coaxial cable:
l Use plastic tape to secure the coaxial cable to the mast at
about 3-foot intervals.
l Use coaxial nail clips every few feet to secure the cable be-
tween the mast and where the cable enters the house.
l Use a 75-ohm grounding block at the point where the co-
axial cable enters the house. Read the Consumer Product
Safety Commission information for grounding instructions.
l Use a wall-through tube to neatly route the coaxial cable
through the walls.
If you use twin-lead cable:
l Be sure the twin-lead cable remains at least 4 inches away
from all metal surfaces.
l Use standoff insulators about every 4 feet. Twist the twin-
lead cable about three turns between standoff insulators.
l Use a 300-ohm static discharge unit at the point where the
twin-lead cable enters the house. Read the Consumer Prod-
uct Safety Commission information for grounding instructions.
CONNECTING LEAD-IN CABLE TO THE ANTENNA
We recommend RG-6 cable, and if you prepare your own cable,
a quality F-connector. You can also use 300-ohm flat, twin-lead
cable. Note: If you prepare your own cable, slide the supplied
matching transformer’s weather boot onto the cable before you
attach the F-connector.
