Installing CAP Ms
Connect the Antenna Cable(s)
The following information regarding antenna mapping and is relevant to all CAP M variants.
• F
or Non-MIMO bands, there is no channel mapping option for the transceiver/antenna port. The
transceiver/antenna port relationship is fixed in hardware.
• F
or MIMO bands, the Era GUI maps MIMO channels according to their AP designation:
– AP0 to
antenna port ANT1
– AP1 to
antenna port ANT2.
• When using
SISO channels on a CAP M that supports MIMO, the system will automatically balance the
number of channels between the two antenna ports, where the first SISO channel is mapped to ANT1, the
second SISO channel is mapped to ANT2, and so on.
Do the following to connect the antenna cables:
1 Obtain 50
coaxial cables that are of sufficient length to reach from the CAP M to the passive antenna. The
end of the 50
coaxial cable that will connect to the ANT or ANT1 connector can be either a push-pull
connector or a threaded connector.
2 I
nstall the passive antennas per the manufacturer’s installation instructions. For MIMO CAP M, if
connecting both ANT connectors, you will connect the CAP L to either two separate external passive
antennas or to two ports on a cross-polarized dual antenna. Each connector supports two RF bands. Use
Table 12 to determine how to connect to the antenna correctly for each CAP M variation.

7820478-000x CAP M 7E/80-85/17E/19 7E/80-85/17E/19 Not Applicable
7820689-000x CAP M 23/23/25/25 23/25 (MAIN) 23/25 (MIMO)
7835269-000x CAP M 6/6/7E/7E 6/7E (MAIN) 6/7E (MIMO)
3 Remove the IP67/EMI blank plug from the ANT connector.
4 C
onnect the passive multi-band antenna to the ANT connector using coaxial cable with the least amount
of loss possible.
• If
the 50 coaxial cable has a push-pull connector, make sure the cable is seated firmly in the ANT
connector.
• If
the 50 coaxial cable has a threaded connector, torque the connector 5 N-m (3.69 ft-lb). Do not
over-tighten the connector.
5 C
onnect the other end of the 50 coaxial cable to the passive antenna installed in Step 2.
6 For a
MIMO installation, repeat Step 1 through Step 5 to connect an antenna cable to ANT2.
