The Barrett 4045 (P/N 4045-00-01 Nato Green) automatic antenna tuner (ATU) is designed for operation in land mobile, marine and base station installations.
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.
Suitable for base station, land Mobile and marine applications.
150 W (digital, voice and data)
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 4049 memory tune feature eliminates the need to re-tune an antenna after a channel change. When returning to a previously tuned channel, the transceiver sets the 4049 with a stored tuning result in less than 100 ms.
The 4045 is fitted with an 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, simplifying the system installation.
The 4045 can be optionally fitted with anti-vibration mounting (P/N BC404501) making it suitable for use in vibration heavy environments.
