Cleaning Connectors
Clean connectors are essential for ensuring the integrity of RF coaxial
connections. Use the following procedure to clean the connectors.
1. Use compressed air or nitrogen
Use compressed air (or nitrogen) to loosen particles on the connector
mating plane surfaces. Clean air can’t damage a connector, or leave
particles or residues behind.
You can use any source of clean, dry low-pressure compressed air or
nitrogen that has an effective oil-vapor filter liquid condensation trap
placed just before the outlet hose. Ground the hose nozzle to prevent
electrostatic discharge, and set the air pressure to less than 414 kPa to
control the velocity of the air stream. High-Velocity streams of compressed
air can cause electrostatic effects when directed into a connector.
2. Clean the connector threads
Use a lint-free swab or cleaning cloth moistened with isopropyl alcohol to
remove any dirt or stubborn contaminants on a connector that can’t be
removed with compressed air or nitrogen.
a. Apply a small amount of isopropyl alcohol to the lint-free cleaning swab.
b. Clean the connector threads.
c. Let the alcohol evaporate, then blow the threads dry with a gentle
stream of clean, low-pressure compressed air or nitrogen.
3. Clean the mating plane surfaces
Apply a small amount of isopropyl alcohol to a new swab and clean the
center and outer conductor mating plane surfaces.
4. Dry the connector
After cleaning, blow the connector dry with a gentle stream of clean
compressed air or nitrogen. Always completely dry a connector before you
reassemble or use it.
5. Reinspect
Inspect the connector again to be sure that no particles or residue.
Always use protective eyewear when using compressed air or nitrogen.
