The Barrett 411 (P/N BC411001) automatic antenna tuner is designed for operation in land mobile and base station installations with Barrett and OEM radio products.
Housed in a fully weatherproof enclosure, the 411 will efficiently tune long wire antennas up to a length of 20 metres, wire loop antennas or whip antennas over a frequency range of 1.5 to 30 MHz. 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.
1.5 MHz to 30 MHz frequency coverage
Compact size
150 Watt (digital, voice and data)
Built in memory tune
ALE 2G/3G compatible
Mil-STD 810G
Designed and manufactured in Australia, he t Barrett 4 automatic antenna 11 (P/N BC411001) tuner is designed for operation in land mobile and base station installations with Barrett and OEM radio products.
Housed in a fully weatherproof enclosure, the 4 will 11 efficiently tune long wire antennas up to a length of 20 metres, wire loop antennas or whip antennas over a frequency range of 1.5 to 30 MHz. Tuning is rapid, typically less than seconds from the first time RF is applied, either whilst the 1.5 operator is talking or when the “Tune” control is activated on the transceiver.
The 4 tuner features a memory facility that stores the configuration required to tune to 11 a frequency. On any subsequent use of a frequency, the 4 reconfigures to the stored 11settings in typically less than 200 milliseconds. A 10 metre RF control cable is available as an optional accessory to order (P/N 4019-00-05)as i an extension adapter kit (P/N ).
