Follow these steps to connect lead-in cable to the antenna.  We recommend
RG-6 cable and, if you prepare your own cable, a quality CF-56 F-connector
(both available at your local Radio Shack store).  You can also use 300
ohm flat, twin-lead cable.

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

Follow these steps if you use coaxial cable.

1.  Thread the ends of the supplied matching transformer through the
    antenna's strain-relief tab.  Then use the supplied washers and wing
    nuts to secure the transformer's leads to the antenna's lead-in
    terminals.

2.  Screw the cable's connector onto the matching transformer.  If you use
    a prebuilt cable without a weather boot, cover the connection with
    weatherproof tape.  Otherwise, slip the boot over the connection.

NOTES:  Use a plastic tape to secure the cable to the mast at about 3
        foot intervals.

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

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

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

Follow these steps if you use twin-lead cable.

1.  Split the cable for a length of about 3 inches.  Then remove about 1/2
    inch of insulation from the ends of the twin-lead cable.

2.  Thread the ends of the twin-lead cable through the antenna's strain-
    relief tab.  Then use the supplied washers and wing nuts to secure the
    twin-leads to the antenna's lead-in terminals.

NOTES:  Allow enough slack between the strain-relief tab and the antenna
        terminals to prevent stress on the cable or terminals.

        Be sure the cable remains at least 4 inches away from all metal
        surfaces.

        Use standoff insulators about every 4 feet.

        Twist the cable about three turns between each standoff.

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

ATTACHING TO THE MAST

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.

Slide the antenna's mast clamp assembly over the end of the mast.  Then
tighten the mast clamp assembly's nuts to hold the antenna in place.  Take
care not to overtighten the nuts.

SETTING UP YOUR MAST

How you set up your mast depends on your specific installation.  refer to
the separate Consumer Product Safety Commission information sheet for
recommended methods.  After you set up the mast, rotate it so the
antenna's shorter elements point toward the broadcast antennas of the
stations you want to receive.
