Jumper J4 must be placed with the following
guidelines (see Figure 2-6):
J4, pins 3-4 for operation with the RJ-11 to BNC
adapter module and mixed systems (2008 and 8000)
with any version of HSDB software.
J4, pins 3-4 for operation with the RJ-11 to BNC
adapter module with 2008 only systems with any
version of HSDB software.
J4, pins 5-6 for operation with the RJ-11 to RJ-11
cable with 2008 only systems with Version 202 or
later HSDB software.

2.10 CONNECTING RECEIVE AND TRANSMIT
ANTENNAS
Receive and Transmit antenna connector loca-
tions are shown in Figure 2-8. Although each trans-
mitter and receiver could be connected to a separate
antenna, this is usually not done because of the large
number of antennas required by a multiple repeater
installation. Therefore, an antenna combining system
is usually used. An example of a combining system
for a five-channel system is shown in Figure 2-5. The
amount of power loss introduced by a combiner
depends on the type of combiner used. If it has a loss
of 3 dB, power output to the antenna is reduced by
half.
