STEP 2.
Grasp both sides of the second
element from the rear of the boom. Lift the
ends of the element just enough to slide
over the other elements to the front and
rear and ROTATE ABOUT 90° COUNTER
CLOCKWISE. See Figure 1.
STEP 3.
Spread all elements
to the lock position, being
sure to alternate the
elements. See Figure 2.
STEP 4.
Turn the antenna
over and repeat steps one
(1) through three (3).
HD7080P & HD7082P ONLY
STEP 5.
Unfold UHF
directors. See Figure 3.
HD7082P SEE FIG. 4
HD4053P SEE FIG. 4A
STEP 6.
Unfold the elements of the front
section of the antenna. Remove the bolt,
hex nut, and element from the tapered end
of the front boom and slide the tapered
end into the front of the rear boom. The
cartridge housing on rear section should
be on the bottom of the rear boom.
Replace bolt, hex nut, and element,
tighten securely.
HD7078, HD7080, & HD7082 ONLY
STEP 7.
Unfold the elements on the
reflector booms first. Then unfold the
reflector booms slowly until they lock in
place. See Figure 5.

NOTE:
To prevent damage in shipping, the second set of elements from the rear of
the boom are folded to the reverse side. You can identify the second from the
rear by the tags attached to them. Follow the directions on the tags carefully.

STEP 8.
To attach the cartridge
housing to the antenna, align the
snaps on the cartridge housing with
the snap holes on the cartridge
housing receptacle on the antenna
and push the housing into the
receptacle until it snaps into place.
See Figure 6.
STEP 9.
Attach the 75 ohm coaxial
downlead cable to the “downlead”
connection on the cartridge hous-
ing. See Figure 6. Slide weather
boot over connectors and boot
collar.
STEP 10.
Loosen nuts on the mast
clamp, slide the antenna over the
end of the mast. Point the front of
the antenna (small end) towards
stations and tighten mast clamp
securely. See Figure 7.
STEP 11.
The 75 ohm coaxial cable
downlead may be secured to the
mast by taping or by using plastic
wire ties.
HOW TO PROVIDE LIGHTNING
PROTECTION FOR TV ANTENNA
AND SET
Step 1.
Mount the lightning arrestor
as close as possible to where the 75
ohm coaxial cable downlead enters
the house. See Figure 8.
Step 2.
The ground wires for both
the mast and the downlead should
be copper or aluminum wire, number
eight (8) or larger. See Figure 8.
Step 3.
The downlead wire from the
antenna to the lightning arrestor and
the mast ground wire should be
secured to the house, spaced from
four (4) to six (6) feet apart. See
Figure 8.
NOTE:
In the case of a “ground up”
antenna installation, it may not be
necessary to ground the mast if the
mast extends four or more feet int
the earth. Consult a TV serviceman
for the proper depth in your location.
