if not necessary, do not use BALUN.
YOU MAY USE NORMAL AMPLIFIER CKT. DEPENDING ON FREQUENCY OF OPERATION.
That is wideband amplifier for TV antenna. If you feed cable TV signal into that one, you will get one big NOTHING because you will overload the amplifier.IanP said:Boosting signal in cable TV can be done in the same way as boosting signal from antennas: you need a low-noise, 44-880MHz and at least 15dB gain amplifier ..
Here is one example:

Then you can use schematic from that link few messages up. But the amplifier must be connected as close as possible to the receiving antenna. If you need to amplify cable TV signal in order to feed two TV sets in your home then you need different amplifier, like that Philips one.ehsanelahimirza said:hamdard said:you must check the signal level and the matcing impedence too.
