Attention:
To minimize passive inter-modulation (PIM) distortion, attention has to be
paid to the physical condition of the connector junctions:
Do not use connectors that show signs of corrosion on the metal surface.
Prevent the ingress of water or dirt into the connector.
Use protective caps for the connectors when not mounted.
Before mounting clean the connectors with dry compressed air.
Before mounting clean the mating surfaces of the connector with a lint-free
alcohol-drenched cloth on a wooden or non-metallic item.
Attach and torque the connectors properly.
Avoid metallic abrasion when mounting the connectors by only screwing the
connecting nut, but not turning the whole connector.
Use a torque wrench to fasten the connector, see above.
Clean the protective caps before mounting for antenna cable replacement.
3.2.6. Cleaning Procedure for RF Cable Connectors
The figures in this chapter illustrate the cleaning procedure and do not show the
actual RU.
1. What is needed for the cleaning?
a. Isopropyl alcohol
b. Compressed air
c. Lint-free wipe
d. Cotton buds
2. Remove protective cap from the RF
connector.
Caution
: Risk of injury by flying particles when compressed air is used. Wear
protective clothing, especially protective glasses.
3. Remove metal chips and small
particles from the mating and inner
surfaces of the connector using
compressed air.
