CATV Amplifier is a equipment which amplify the signal.It is used in Headend as well as in cable tv field.This is boosting device which boost the signal and carry it to long distance in field.It can be also use in headend to amplify the signal received from QAM. This output goes into the different transmitters to send signal in field.There are different kind of amplifiers that work for different frequencies like 550 MHz,750 MHz and 890 MHz. Thus it is also known as Headend Equipment<\/a><\/span>.<\/p>\n\n\n\n

Need Of Shifting CATV Amplifiers<\/h2>\n\n\n\n

Every industry needs to upgrade. Like this cable tv industry needs to upgrade its field amplifiers.We were using the catv amplifier of 550 MHz that is limited to the 67 analog channels. As we all knows number of channels are increasing day by day now we need to use more frequencies.To transmit these new frequencies in field we need to use 750 MHz amplifiers or 890 MHz amplifiers. 890 MHz amplifiers are capable to amplify 106 analog channels.So for digital headend if you are using frequencies more than 538 MHz then you should go for 890 MHz amplifier for better performance in field.<\/p>\n\n\n\n

Problem In Replacing 550 MHz to 750 MHz Amplifiers<\/h2>\n\n\n\n

If we are using traditional amplifiers of 550 MHz with 500 series trunk coaxial.Then the amplifier distance is 400 meter.<\/p>
