TERRA SA-91L Multiswitch Line Amplifier 9 Inputs / 9 Outputs

The TERRA SA-91L is a professional multiswitch line amplifier designed for distributing satellite and terrestrial TV signals in multi-dwelling units and small to medium-sized headend systems. With 9 inputs and 9 outputs (8 satellite + 1 terrestrial), it compensates for signal losses in long cable runs and provides stable, high-quality signal distribution.

Advantages

• Compensates for signal loss in multiswitch systems
• 9 inputs and 9 outputs for flexible signal routing
• Adjustable gain (0-15 dB) for both satellite and terrestrial paths
• Low noise figure ensures excellent signal quality
• DC pass on satellite lines for LNB powering (13V/18V, 0/22kHz, DiSEqC)
• Compact metal housing for durability and shielding

Suitable for

• Multi-dwelling units (apartment buildings, hotels)
• Small headend systems
• SMATV installations
• Any installation requiring signal amplification after a multiswitch
