Antenna

Antenna connection is made via a 5 metre RG58 low loss cable,

which is terminated with a standard TNC 50-ohm male connector.

If two antennae are supplied, each antenna will have its own cable.

An antenna unit has an internal LNA (low noise amplifier) which is typically

the antenna socket on the rear panel. Therefore, care must be taken not to

connect or disconnect an antenna when power is on.

Data

The Data port is a standard DB9 female socket. The external GPS is plugged into

this port. A laptop computer may also be plugged into the Data Port to view the

RTCM output.
