rectangular shape to the antenna when laying down the

wire.

Step 5: Feed one end of the Road Loop wire to the ATU.

IMPORTANT! The total length of lead-in wire (the Road

Loop wire from the Road Loop to the ATU) must not

exceed 20 feet. Do Not Twist the wire as you run it from

the Road Loop to the ATU.

Step 6: Insert the end of the Road Loop wire at the ATU into one

side of a binding post-to-BNC connector (Figure 24).

Tighten the binding post terminal to secure the lead.

Step 7: Connect the BNC-end of the Road Loop wire to the

Antenna TX connector on the ATU.

Step 8: Carefully feed Road Loop wire on toward the loop marked

on the roadway. Secure the wire with duct tape as you

proceed.

Step 9: At the loop feed point, begin to lay wire around the loop

(using the concrete nails to maintain the corners). Again,

secure the loop to the surface with duct tape.

Step 10: When back to the feed point, continue around the loop a

second time if the Road Loop is shorter than 36 feet (do

not allow the two wires to twist) and return to the feed

point.

IMPORTANT! For a Road Loop wider than 36-feet, use

only a single loop of wire.

Step 11: After one or two complete loops (see note above),

continue to lead the wire back to the ATU or junction point.

Do not allow the wires to twist.

Step 12: Carefully review the installation to this point. If everything

is correct, cut away the excess wire, trim and attach the

other end of the Road Loop wire to the other half of the

binding-post-to-BNC connector (Figure 25).
