KP39A using supplied GPS antenna with SMA termination


 KA07 GPS antenna with 10 metres cable can be installed in place of the supplied 39A GPS antenna together with a BNC to SMA adaptor if GPS reception is not 100%  or just use an existing GPS antenna with the adaptor. Whilst the supplied GPS gives excellent results, any antenna is only as good as the signal it receives. Deep down in a boat, particularly one constructed in steel or alluminium, an external antenna may be required.
