NovAtel L1 GPS/ L1 GLONASS Antenna

Model 504

- User Information -

DESCRIPTION

The Model 504 GPS/GLONASS antenna 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 504 GPS/GLONASS antenna is an active antenna designed
to operate at the GPS L1 frequency 1575.42 and the GLONASS L1
frequency range 1602.0 - 1615.5. The microstrip receiving antenna
element is 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 5/80
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.
