Part Number : NTX-TR870
NTX-TR870 is an external amplifier with three outputs used to transmit analog signals , Digital, Data, Internet, IPTV in Cable TV.
The equipment has high-tech integrated circuits, temperature extended circuit has automatic gain control AGC, ADU (Automatic Driver Unit) function is selected high-quality materials to manufacture anodized chassis and rubber seal.
|
- The direct and return ways have amplifiers of Gallium Arsenurio Hybrids that have high gain, low noise, high gain and ratio C / N. The frequency of operation is 870 MHz.
- Pads and equalizers are compatible with Motorola.
- The source voltage is self-regulating from 38-90 vac.
- It has automatic gain control AGC.
- It has an ADU (Automatic Driver Unit) to which a carrier at 499.25 MHz (Channel 70) from the head-end to achieve optimum gain control function of the degradation of the signal of TV and data caused by the temperature variation of this exposed coaxial cable.
