BC404701 Barrett 4047 HF Antenna Kit, Horizontal Dipole Automatic Tuning, for Fixed Base-Station

BC404701 BARRETT 4047 HF Antenna Kit, Automatic Tuning, Horizontal for Base-Station

The Barrett 4047 Horizontal Dipole Automatic Tuning HF(P/N BC 404701) is specifically designed to interface with Barrett 4000 series HF transceivers.

It is designed for base station applications where space is limited but high performance is still required.

Mounted on a standard 50mm pole the antenna can be, mounted as close as 6 metres from the ground making it extremely easy to instal . With a packed length of only 2.1 metres the antenna can be transported by air. For compatible ,
masts please download the Barrett Mast Guide.

The Barrett 4047 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.

Features

• 1.5 – 30 MHZ Tuning Range
• Compact Size
• Easy installation in space restricted locations –
• 150 W ( voice and Data) Digital,
• Internal GPS
• ALE 2G/3G Compatible
• Memory Tune (100 ms)
• Mil-STD 810G

Providing a frequency coverage of 1.5 to 30MHz, the Barrett 4047 features rapid tuning (typically less than 1.5 s) and low
power consumption capabilities.

When paired with a Barrett 4000 series HF Transceiver, the 4047 memory tune feature eliminates the need to retune an
antenna after a channel change.

When returning to a previously tuned channel, the sets the 4047 with a transceiver stored tuning result in less than 100ms.
