@HANKMARS Re: Post #9. A balun! Do you even know what that is, or what it is used for? Show us a schematic of what you are trying to DO instead of how you think it should be done.
If you are trying to move CCTV video from point A to point B, you use coaxial cable, either 75 Ω characteristic impedance or 50 Ω characteristic impedance, and a proper line-driver and a line-receiver amplifier at each end of the cable. You don't use CAT5 Ethernet cable, or ribbon cable of any kind, or whatever cable happens to be available. If your "customer" has purchased the wrong cable, that's his problem not yours. Advise him to take it back and purchase a spool of 75 Ω coaxial CCTV cable. Simplify your life by having him purchase it with coaxial connectors already attached.
These are just buzz words I have thrown at you, for it is obvious you have no idea what you are doing. Ditch the 747 op-amp. It is totally inappropriate. Video amplifiers are generally not a good candidate for bread-boarding. Pay attention to what
@duke37,
@WHONOES,
@Audioguru and perhaps others with real experience have to say.
Me? I'm old and I haven't farkled with this sh!t since they quit broadcasting NTSC video over the air to my rabbit-ear antennas. And BTW, there is no way anyone would EVER use a class-C amplifier to boost ANY sort of video signal. Video was ANALOG until fairly recently. Class-C amplifiers only amplify the peaks of the input signal and are generally used only in radio frequency applications.
