CONNECTING TO YOUR TV/VCR

You can use 75-ohm coaxial cable or 300-ohm twin-lead cable to connect the
antenna to your TV or VCR.  For the best reception, we recommend 75-ohm
coaxial cable.

NOTE:  If your twin-lead cable is weathered or cracked, we recommend you
       replace it with 75-ohm coaxial cable.

Connecting With 75-ohm Coaxial Cable

Follow these steps to connect the antenna using 75-ohm coaxial cable.  We
recommend RG-6 cable and, if you're preparing your own cable, a quality
CF-56 F-connector (both available at your Radio Shack store).

NOTE:  If you prepare your own coaxial cable, slide the supplied matching
       transformer's weather boot onto the cable before you attach the F-
       connector.

1.  Thread the ends of the supplied 75-to-300-ohm matching transformer
    through the antenna's plastic strain relief.

2.  Use the supplied hardware to attach the matching transformer to the
    antenna's lead-in terminals, which are labeled CONNECT LEAD-IN HERE.

3.  Connect the coaxial cable's F-connector to the transformer.  then
    slide the weather boot over the connection.  If you are using pre-
    built cable without a weather boot, cover the connection with weather-
    proof tape.

4.  Route the coaxial cable down the mast, into the house, and to your
    TV/VCR.  Follow these hints as you route the cable.

    Use plastic tape to secure the cable to the mast about every 3 feet.

    Use coaxial nail clips every few feet to secure the cable to walls.

    Use a 75-ohm grounding block to ground the coaxial cable at the point
    where the cable enters the house.

    Use a wall-thru tube to neatly route the cable through the walls.

Your local Radio Shack store sells all the necessary accessories for
routing the cable.

5.  Connect the cable to your TV/VCR as follows.

    If the TV/VCR has only 300-ohm terminals, use a 75-to-300-ohm
    splitter, such as Cat. No. 15-1139.

    If the TV/VCR has 75-ohm VHF terminal and a 300-ohm UHF terminal, use
    a 75-to-300/75-ohm splitter, such as Cat. No. 15-1252.

    If the TV/VCR has a 75-ohm combined VHF/UHF terminal, connect the
    cable directly to the terminal.

Connecting with 300-Ohm Twin-Lead Cable

Follow these steps to connect the antenna using 300-ohm twin-lead cable.

1.  Use a wire stripper to remove about 1/2 inch of insulation from the
    end of the twin-lead cable.

2.  Thread the end of the twin-lead cable through the antenna's plastic
    strain relief.

    NOTE:  Allow enough slack between the plastic strain relief and the
           antenna terminals to prevent stress on the twin-lead cable or
           terminals.

3.  Use the supplied hardware to attach the twin-lead cable to the
    antenna's lead-in terminals, labeled CONNECT LEAD-IN HERE.

4.  Route the twin-lead cable down the mast and into the house using
    standoff insulators about every 4 feet.  Follow these hints as you
    route the twin-lead cable:

    Be sure the twin-lead cable remains at least 4 inches away from metal
    surfaces.

    Twist the twin-lead cable about 3 turns between stand-offs.

    Use a 300-ohm static discharge unit to ground the twin-lead cable at
    the point where the wire enters the house.

Your local Radio Shack store sells all the necessary connection
accessories.

5.  Attach the twin-lead cable to your TV/VCR's antenna terminals.
