This subscriber amplifier increases the signal level by 15 dB and can compensate for the attenuation when distributing cable TV (CATV). This signal attenuation is caused by the addition of a distributor and/or by longer cables. The amplifier can be used for operation in modern cable networks that use a frequency range up to 1218 MHz and provide cable Internet at gigabit speed. The data signals in the frequency range 5 to 204 MHz are not amplified so that they don't interfere with the return path to the network operator. This upstream for Internet and telephone is attenuated in the frequency range 5 to 204 MHz with only -1 dB.
