Antenna voltage settings
The available antenna voltage shall be configured depending on
which antenna that is used together with the transceiver. It Table
33 the configuration based on selected antenna is listed.

TT-3001B
High antenna voltage = 14V DC
TT-3005A
High or low antenna voltage
TT-3005M
Low antenna voltage = 9 V DC
Table 33 Antenna voltage configuration
When the Transceiver is transmitting there will be +28 V DC on
the antenna connector. When the Transceiver is receiving there
will be 9 V DC or +14 V DC on the antenna connector.
If a TT-3001B opt.001 Antenna type is used, and it is supplied with
+9 V DC, it will not be operational. The antenna will however not
be damaged by this.
In general will a low antenna voltage will lead to a lower power
consumption of the antenna.
Low antenna voltage is selected by issuing the command:
“s
e —f 0”
in the transceiver terminal mode (described in section 4.1) and
high antenna voltage is selected by issuing the command
“se —f 1”
in the transceiver terminal mode.
