Coaxial Cables and Conduit
Communication between the IDentity Flex reader and the remote antennas is by
means of coaxial cable. There are two cables from each antenna to the reader –
one for the transmit signal, one for the receive signal. Conduit diameter must be
sufficient to house both cables and any other communication cabling required at
the read location. Power cables should not be housed in the same conduit as
these cables.
Cable selection is dependent on the distance between the reader and the remote
antennas. It is important to establish the cabling requirements in conjunction with
the Pre-Installation Questionnaire. See the Site Planning Guide section on
cabling starting on page 17.
Below is a summary of important installation tips:
• If the cable run between the reader and the remote antenna is less
than 50 feet, use Belden 8240 (RG-58/U) cable.
• If the cable run between the reader and the remote antenna is more
than 50 feet (to a maximum of 200 feet) use Belden 9913 cable.
• For Belden 8240 (RG-58/U) cable, installers will need to provide
connectors. SIRIT can provide these by quoting part # IDFLEX-
CONN-RG-58/U. Each kit contains enough connectors to install one
antenna - two (2) Amphenol 82-5375’s and two (2) AMP 226600-1’s.
• A pre-connectorized cable kit is also available from Sirit, Order PN
IDFLEX-CONN RG58/U-60K. Each kit contains 2 – 50’ lengths of
RG58/U cable with “N” connectors installed and 2 crimp mini-uhf
connectors not attached.
• For Belden 9913 cable, installers will need to convert from 9913 to a
mini UHF connector at the reader end. SIRIT can provide a cable
converter kit as an option by quoting part # IDFLEX-CABLECON.
Each kit contains enough connectors for one antenna.
• For Belden 9913 cable, installers will need to provide connectors.
SIRIT can provide these by quoting part # IDFLEX-CONN-9913. Each
kit contains enough connectors to install one antenna - four (4)
Amphenol 82-202-1006 connectors.
• Installers must use the proper crimping tool to install the above
connectors. You can purchase this item locally (Amphenol CTL-5) or
SIRIT can provide this as an option by quoting part # IDFLEX-CRIMP.
• SIRIT recommends that outside connectors be weather-proofed by
applying proper weather-proofing tape. First, mastic tape is applied
over the dry connector then covered with electrical tape. Tape kits are
available from SIRIT by quoting part number IDFLEX-CONN-WKIT.
