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
powered by 5V DC. When the 3510LR is powered up, this voltage is present at
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.
