NovAtel L1 GPSAntenna™
Model 531 Rev 2
– User Information –
DESCRIPTION
The Model 531 GPSAntenna is intended for surveying and other
kinematic positioning applications. The sealed radome allows the
antenna to be used in severe weather and hostile environments, and
the unit’s compact size and light weight ensure its portability.
The Model 531 GPSAntenna is an active antenna designed to operate
at the GPS L1 frequency, 1575.42 MHz. The microstrip receiving
elements are coupled to filters and a low-noise amplifier (LNA). The
unit is optimized to receive right-hand-circularly-polarized signals, and
its radiation pattern is shaped to reduce signals arriving at low
elevation angles; these features decrease the errors associated with
electromagnetic interference and multipath.
Both the input DC power and the output RF signal flow over a single
coaxial cable that is connected to the unit’s TNC female connector.
The antenna baseplate features a permanent adaptor that accepts a 5/8
0
x 11 threaded bolt; this allows the antenna to be used on a tripod.
Ï Caution: overtightening a bolt into the base may damage the base.
