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 12V DC. When the 3100LRS 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. Data logging can be carried
out by plugging a Psion data logger into this port. A laptop computer may also
be plugged into the Data port for data logging and position information retrieval.
