The Barrett 4045 Black BC ( P/N 404501)automatic antenna tuner (ATU) is designed for
operation in land mobile, marine and base station
installations with Barrett transceiver products.
Housed in a fully weatherproof (IP67) enclosure, the 4045
efficiently tunes long wire antennas up to a length of 20
metres, wire loop antennas or whip antennas over a frequency range of 1.5 to
30MHz. Tuning is rapid, typically less than 1.5 seconds from the first time RF is
applied, either whilst the operator is talking or when the "Tune" control is
activated on the transceiver.
When paired with a Barrett 4000 series HF Transceiver, the 4045 memory tune
feature eliminates the need to re-tune an antenna after a channel change. When
returning to a previously tuned channel, the sets the 4045 with a transceiver
stored tuning result in less than 100 ms. is fitted with an internal GPS. This It
internal unit can be used to provide GPS data as part of a GPS tracking network
without the need to install a separate GPS, simplifying the system installation..
