Every Class B Transceiver need a own GPS antenna for position fix and
time synchronizing. With this integrated antenna there are no needs to
install an external GPS antenna.
Mount the easyTRX2 with IGPS on you map table with view to the sky. We
get a good reception beneath it. If you are not sure where you should fix
the unit just try it befor. To do this please program MMSI, ship name,
callsign in the unit. If you connect then power and VHF antenna the
easyTRX2 with IGPS should go to “All OK” and the green LED illuminate.
Following points could create a bad GPS reception:
Cable on the top of internal GPS antenna within 30cm
Boat with metal
Windows with a thin metal surface on it.
If you try everything and there is also no GPS reception of course you are
able to mount also an external antenna to it.
