RF Connector Care
3. Using two wrenches with an angle greater than 90° causes the
connector devices to lift up and tends to misalign the devices and
stress the connectors. This becomes more of a problem when there
are several devices connected to each other.
4. Breaking the handle fully can cause the wrench to kick back and
may loosen the connection.
Disconnection Procedure
1. Use an open end wrench to prevent the connector body from
turning.
2. Use another wrench to loosen the connector nut.
3. Complete the disconnection by hand, turning only the connector
nut.
4. Pull the connectors straight apart without twisting or bending.

RF Connector Care
Most coax connectors are assembled into a system and forgotten, but
some, especially on test equipment are used almost continuously. The
care and cleaning of these connectors is critical to accurate and reliable
performance. Remember that all connectors have a limited life time and
usually a maximum connect/disconnect specification, typically about
5,000 connections. Most will last well beyond this number, but poor
usage and poor care can destroy a connector well before that number.
Good connector performance can be achieved with the following:
• Periodic visual inspection
• Cleaning
• Proper connection and disconnection techniques using torque
wrench
• Appropriate gauging techniques
Visual Inspection
To ensure a long and reliable connector life, careful visual inspection
should be performed on the connectors before they are used on a
particular job at a minimum of once per day when the item is being
used. A “good” connector may get damaged if it is mated with a “bad”
one.
