Optional Dipole Antenna Installation

If the 20-foot cable run to the ATU prevents you from mounting the
Dipole Antenna within specifications. You can run connect the Dipole
Antenna directly to the Reader. Remember to keep the Dipole
Antenna within 20 feet of the Road Loop Antenna.

Step 1: 

Measure the cable distance between the Dipole Antenna
and the Reader. It should not exceed 

100 feet

.

Step 2: 

Cut a length of cable that equals the cable length
measured and attach the BNC connectors to both ends of
the RG-58/U coaxial cable (See 

Appendix A: Coaxial

Cable

, page 101).

Step 3: 

Connect one end of the cable to the Dipole Antenna.

Step 4: 

If the Dipole Antenna will be exposed to the weather, treat
the connection with RTV rubber silicone sealant after
everything is installed.

Step 5: 

Connect the other end of the coaxial cable to the

 RX

connector on the Reader.

Note: Do not dress-wrap or tie-down the cables until the
system has been tested.

Step 6: 

Turn on the system and adjust the ATU in accordance with
the instructions in the 

Maximizing Antenna Performance

with the ATU 

section, page
