Connecting The Antennas To The Cisco Fm3200 Base; Rpsma Antenna Connections - Cisco FM3200 Base Installation And Configuration Manual

4.2.3. Connecting the antennas to the Cisco FM3200 Base

RPSMA antenna connections

IMPORTANT
The FM3200 Base is ingress-protection rated to standards
specified by EN 50155 and EN 45545.
To ensure the FM3200 Base remains
dustproof, follow all instructions in this section.
Following the instructions in this section will also ensure that
the FM3200 Base is well prepared for any ingress-protection
testing.
Radio antennas are connected to the Cisco FM3200 Base using reverse-
polarity sub-miniature version A (RPSMA) connectors.
WARNING
Before activating the unit, make sure that all RF feeds are
securely connected to an appropriate antenna. Never activate
any transceiver unit that is not connected to an antenna.
Cisco uses copper-tin-zinc-plated female RPSMA connectors. These
connectors are capable of corrosion resistance that exceeds the demands
imposed by ASTM B117
immune to corrosion, provided that they do not remain in contact with
standing salt water for long periods of time.
In the opinion of Cisco engineers, certain brands of RPSMA plug
have shown outstanding performance. We can confidently recommend the
following brands:
• Amphenol
• Huber+Suhner
• Rosenberger
• Radiall
CAUTION
Do not remove the protective rubber sleeve
35)) from any female RPSMA plug if an antenna will not be
connected to the plug. Unprotected RPSMA contacts that are
exposed to water will oxidize, causing degraded performance.
