Amplificador de início de cascata JULTEC JAL0425WN com fonte de alimentação

The JULTEC JAL0425WN is a professional cascade start amplifier designed for SAT-IF distribution systems. It enables the cascading of multiple multiswitches by providing amplified SAT signals and a passive terrestrial path. The amplifier features four SAT inputs (VL, HL, VH, HH) and one terrestrial input, with corresponding outputs for cascading. It includes an external power supply (19V DC, 2A) and supports LNB power supply with selectable 14V/18V and 22kHz tone. With a typical SAT gain of 25 dB and a frequency range of 950-2400 MHz, it ensures reliable signal distribution for large installations.

Advantages

High-quality amplification for SAT-IF signals, easy cascading of multiple multiswitches, integrated slope compensation, and robust LNB power supply up to 1.5A total current. The passive terrestrial path ensures minimal signal loss for terrestrial TV signals.

Suitable for

• SAT-IF distribution systems in multi-dwelling units
• Cascading JULTEC JPS series multiswitches
