TMA2Q/LPC2Q Quadrature Tower Mounted Amplifier Instruction Manual

Caution
: The LPC2Q is equipped with reverse polarity input protection on the internal power supplies; however,
do not connect anything to the dc power input unless its polarity and voltage are known to be correct.
Caution
: Observe anti-static discharge practices at all times.
The LPC2Q assembly does not have mounting brackets, and it should not be installed where exposed to the
weather or direct sunlight. The LPC2Q should be located at a convenient indoor location close to its power
source to minimize voltage drop. The minimum input voltage to the LPC2Q is 11.0 Vdc. It is not necessary to
install the LPC2Q near the receiver but care should be taken to minimize transmission losses. As with the
TMA2Q, all RF connections on the LPC2Q are female type N and the corresponding cables require male type N
connectors (figure 6). Connectors should be finger-tight; never use a wrench or pliers on the type N connectors.
The dc power connection to the LPC2Q is through a 2.1 x 5.5 mm coaxial power jack and plug (center positive). A
matching plug is supplied with the TMA2Q/LPC2Q. The user must solder insulated conductors to the power plug
and provide power supply connections. The power plug can accommodate 18 AWG (1 mm diameter) or smaller
insulated stranded conductors.
IMPORTANT: The power plug must be wired with center positive.
Double-check the polarity before inserting
the plug; see caution above.
The allowable input voltage range is 11 to 15 Vdc. The dc power source should be
filtered and capable of supplying 300 mA.
If a power supply was purchased with the TMA2Q/LPC2Q, it includes a proper power plug.
