U-120 UHF Antenna  (150-1662)       Preparation       Faxback Doc. # 7371

BEFORE YOU BEGIN

Before you begin installation, read this manual and the separate Consumer
Product Safety Commission information sheet.  For your safety and
convenience, plan each step of installation and purchase the necessary
hardware in advance.  The order in which you perform the steps and the
hardware required depends on the mounting and connection methods you use.

PREPARING THE ANTENNA

Prepare the antenna for installation as follows:

1.  Grasp each element near its pivot point and unfold or turn it so it
    locks into place.

2.  Fold out the wing booms so they snap into place.

3.  Use the supplied hardware to loosely attach one of the supplied mast
    clamp assemblies to the antenna's main boom.

4.  Loosely attach the other mast clamp assembly to the cradle boom.

    Then attach the H-blocks to the antenna.

5.  Insert the supplied end plugs into the ends of the cradle boom and
    each antenna boom.

ATTACHING TO THE MAST

Attach the cradle boom and antenna to the mast as follows.

1.  Slide the antenna mast clamp over the end of the mast about 10 inches
    from the top of the mast, and tighten the nuts just enough to hold the
    antenna in place.

Note:  If you are adding the UHF antenna to a VHF antenna, mount the
       UHF antenna on the mast at least 42" (1.1m) below the VHF
       antenna.

2.  Slide the cradle boom's mast clamp assembly over the end of the mast,
    and snap into the H-Blocks of the antenna.  Tighten the nuts just
    enough to hold the antenna in place.  The strain relief bracket and
    antenna lead-in terminals should face down.

3.  Position the antenna so the shorter elements point toward the stations
    you want to receive.

4.  Tighten the nuts for both mast clamp assemblies, but do not over-
    tighten.

5.  If you are installing the UHF antenna as a single antenna with an
    antenna rotator, follow its instruction sheet for positioning the
    antenna.

ADDING UHF ANTENNA TO A VHF ANTENNA

1.  Connect the UHF antenna to a VHF antenna by cutting the twin-lead
    cable of the VHF antenna at 70" (1.8m) down (long enough to reach the
    UHF antenna).

2.  Feed both loose ends of the twin-lead cable thru the strain relief of
    the UHF antenna and connect to terminals labeled CONNECT LEAD-IN HERE
    using supplied hardware.

3.  In some locations it may be necessary to use a VHF/UHF combiner such
    as Radio Shack Cat. No. 15-1137 to receive a satisfactory picture.
