BSRF AS-84

BSRF AS-84

The BSRF AS-84 is a compact, active diversity combiner/splitter designed for use with up to four diversity receivers. The device offers flexible antenna configurations and selectable filtering to optimize reception quality.

Key Features

• Antenna zoning: Choose the diversity port (PORT 1, PORT 2, or both) to combine antenna signals and cover different areas.
• Selectable filtering: Switch between a wideband filter (470-700 MHz) and an adjustable narrowband filter (50-70 MHz bandwidth, tunable from 470 to 740 MHz in 32 steps) for optimal signal processing.
• Integrated DC power: Activate DC feed on input ports; the 12V power is regulated and protected against overload, suitable for active antennas.
• Signal monitoring: Monitor the power on each channel via a high-contrast OLED display to secure reception.
• Compact and robust design: Suitable for both portable and fixed setups, with a stainless steel clip for flexible mounting.
