2.2.7 Radio Module
The radio module houses two high performance radio transmitters and receivers. These modules are specific to either the
VHF or UHF bands and will be pre fitted based on the band of the GoBox ordered.
2.2.8 Duplexer/Bypass Module
The Duplexer/Bypass module is available in two types:
Duplexer (Standard) Module
Duplexer Bypass Module
The Duplexer (Standard) Module contains a duplexer which is tuned to the centre frequencies requested at the time of
order to maximise RF performance.
Additional duplexers in the same band can be ordered and swapped within minutes. Additionally the GoBox can auto sense
the installed duplexer and select the correct operational profile without any user interaction.
To change the duplexer, ensure the GoBox is turned off and all power sources removed. Remove the duplexer, by turning
the locking screws counter clockwise until the duplexer module can be lift up and out of the GoBox.
When installing a duplexer, take care to ensure that the duplexer is fully inserted. To avoid damaging the module, the
GoBox or the locking screws, do not apply excessive downward force. Alternate between pushing the module in and
turning the locking screws clockwise.
The Duplexer Bypass Module can be fitted instead of a standard duplexer module. When a Duplexer Bypass Module is
fitted the transmit RF output is sent to the standard Tx/Rx RF connector, and the receive RF input is from the Rx only 2
nd
RF
connector (option). See RF Connectors 2.2.3.4 for additional information.
The GoBox when first unpacked will not have any operational profiles to execute. Until the GoBox has been
configured, the power/status LED will continue to flash, indicating it is in the programming state.
!
The GoBox radio modules have been designed to run at high temperatures in order to support the power output
and high duty cycles typical of a heavy use repeater/base station. Care must be taken if the GoBox has been
running for several hours supporting a large volume of calls. The front panel of the radio module can exceed 50
o
C.
!
The duplexer may become hot during operation, particularly at high output power or high duty cycles. Care must
be taken if the GoBox has been running for several hours supporting a large volume of calls. The front panel of the
duplexer module can exceed 50
o
C.
!
The duplexer is not hot swappable. You must ensure the GoBox is powered down, batteries removed and all
external power sources disconnected before removing the duplexer module.
!
When the Duplexer Bypass Module is used in with Rx Only 2
nd
RF Connector, the receiver will require protection
from the transmitter in full duplex modes of operation. The protection can be provided by 3
rd
party duplexer/
filters.
