8 OPERATION
Operation of the Antenna Splitter is automatic and requires no user intervention.
●
During operation, the Antenna Splitter will share the signals received (RX) at your VHF Antenna
between both the VHF Radiotelephone and the AIS Transponder
●
When either connected device transmits (TX), the Antenna Splitter will automatically route the
transmission to the Antenna
●
VHF Radiotelephone transmissions (including DSC transmissions) are given priority over AIS
transmissions
NOTE: It is not possible for both connected devices to transmit simultaneously using a single VHF
Antenna. Whilst you are talking on your VHF Radiotelephone no AIS position reports will be
transmitted.
