Dipole Antenna
Problem: The Dipole Antenna has diminished or no range
Step 1:
Ensure that RG-58/U with 100% foil shield coverage is
used.
Step 2:
Ensure that the cable lengths are within specifications: no
more than 80 feet between the Reader and the ATU and
no more than 20 feet between the ATU and the antennas.
Step 3:
Ensure that the connectors are well fastened and in good
order.
Step 4:
Ensure that TX is connected to TX and RX is connected to
RX on the Reader, ATU and antennas.
Step 5:
Check the continuity of the cables. See page 87 for details
on checking continuity.
Step 6:
Hook the Dipole Antenna directly to the Reader to test its
range.
Step 7:
Swap the nonfunctioning Dipole Antenna with another
Dipole to check if it is a Dipole Antenna problem.
Bar Antenna
Problem: The Bar Antenna has diminished or no range
Step 1:
Ensure that RG-58/U with 100% foil shield coverage is
used.
Step 2:
Ensure that the cable lengths are within specifications: no
more than 80 feet between the Reader and the ATU and
no more than 20 feet between the ATU and the antennas.
Step 3:
Ensure that the connectors are well fastened and in good
order.
Step 4:
Ensure that TX is connected to TX and RX is connected to
RX on the Reader, ATU and antennas.
Step 5:
Ensure that the Bar Antenna has been positioned
correctly. The Bar Antenna is for indoor use only.
Step 6:
Ensure that the ATU is tuned. See page 73 for information.
Step 7:
Check for continuity on the connectors, cable, loop and
dipole. The loop should have continuity. The dipole should
be checked from the end of the dipole to the terminal and
should have continuity. Check to see if continuity goes
from loop to BNC connector. Check Dipole continuity from
terminal block to BNC connector. See page 87 for details
on checking continuity.
