the type and fault. Store it properly in the carton. Label the carton
for easy identification and handling in the future.

Make a new connector in the way as described in the manual for
making connector in the package of the connector.
v.

disconnection through the multimeter.
Note:

of sharp tools.
Pay attention to the handling of the feeder leftover. If sundries such as copper
bits are filtered into the connector, the performance of the antenna feeder system
will be influenced.
During operations high above the ground, protect the tools being used to
prevent them from dropping and hurting personnel on the ground.

Connect the new connector and test the antenna feeder indexes.
