BARRETT 2019 AUTOMATIC TUNING HF ANTENNA
Introduction
The Barrett 2019 antenna plugs
directly into the “ATU” and “RF”
connectors located on the trans-
ceiver using the cables supplied.
The Barrett 2019 antenna can be
fitted with an optional internal GPS.
This internal unit can be used to
provide GPS data as part of a GPS
tracking network without the need
to install a separate GPS, thereby
simplifying the system installation.
The GPS unit is connected via the
integrated coaxial, control and
GPS cable supplied with the Bar-
rett 2019 antenna. The transceiver
interface cable is supplied with two
connectors as standard even if the
GPS unit is not fitted.
When paired with a Barrett 4050
HF SDR Transceiver, the 2019 has
memory tune capabilities limiting
the transceiver’s need to retune an
antenna after a channel change.
When returning to a previously
tuned channel, the 4050 loads the
2019 with a stored tuning result
and evaluates the resulting VSWR. If
the VSWR is outside acceptable lim-
its, the 4050 will perform a retune.
Please note: On first turn on of equip -
ment, the GPS unit can take up to 10
minutes to acquire Almanac data.
