Chapter 2 Installation and Configuration
Upgrading Existing Housing Seizures
The GainMaker Line Extender modules have a higher current-carrying capacity than
some earlier line extender products. If you are replacing an earlier line extender with a
GainMaker Line Extender, you must upgrade the housing to handle the higher current
demands.

The 15 A housings have silver-plated 0.063 in. diameter pins in the seizures. The plastic
material in the seizures and anvils are glass-filled in order to handle the higher AC
currents, as well as higher temperatures.

diameter pins rated for higher-current applications.
Note: The RF connectors, seizures, and anvils are coded blue for ease of identification.
To Install the New Housing Seizures
Complete the following steps to upgrade an amplifier housing to 15 A current capacity.
Important: The power shunts must be removed before installing the unit into a powered
housing. With shunts removed, it reduces the power surge to the components and
F-connectors.
CAUTION:
RF connectors and housing seizure assemblies can be damaged if AC shunt
RF connectors and housing seizure assemblies can be damaged if AC shunt
power directors are not removed from the amplifier before installing or
removing the amplifier module from the housing.
1
If an amplifier module is installed in the housing, you must remove it before
continuing. Refer to Removing the Amplifier Module from the Housing (on page 35).
2
Using a seizure wrench, part number 143190, remove the seizures from the housing.
See the diagram below.
