GPS Antenna Connector
The connector used on the SF-2110 is a TNC female,
labeled ANT 1 on the rear panel of the sensor as
shown in Figure 9.
‡
Both the GPS antenna port (ANT 1)
and the StarFire antenna port
(ANT 2 - SF-2110R only) provide
5.0VDC, 150mA. Do not disconnect
the antenna when the GPS unit is
powered on.
The system is supplied with 12ft (3.6m) of RG58/U
cable (P/N 94-310261-3012LF). The cable is fitted
with two straight male TNC connectors.
The cable length between the antenna and SF-2110
should not exceed 7dB loss at 1.575GHz for optimum
performance, though the system may tolerate up to
10dB of cable loss with minimal performance. Lower
elevation satellite tracking suffers the most with more
than 7dB insertion loss.
