What do the different colors on AV cords mean?
There are various methods to connect AV equipment, but since you are after colours, it rounds it down to 2 scenarios:Composite video, where the entire video signal’s components are modulated into one, single, signal. The consumer industry has opted for the colour yellow, to represent a video connector which carries this type of signal. This will appear as a Yellow female RCA (aka Cinch) connector on the back of AV equipment, and you would interconnect the equipment with one of these:The White and Red colours are used to represent Audio Line inputs and/or Outputs. The colour Red is conventionally used for the Right Channel of a stereo signal, as Red and Right both start with the letter R. The other channel (Left) will appear on a White connector.The other type of AV connectivity which uses colour is the:Component video, where the video signal is sent as separate components, known as Y, U, V, or on consumer equipment, Y, B, R, as per the picture below. The Y signal is in fact the Green component, whilst the U signal is the difference between the Green signal and the Blue signal (hence the B-Y) in the picture, and the V signal is the difference between the Green signal and the Red signal (hence the R-Y). It takes up less bandwidth to code one information in full (Green) and code the difference for the other two colours, than to code all three in full.So your connecting cables would also be RCA, but you’d need a total of five to carry picture and sound:Something like this to connect the video:And something like this to connect the audio:All other AV cables are “all-in-one” and therefore don’t use colour codes (VGA, S-VGA, HDMI, S-Video, …). Only HDMI carries audio alongside the video information, so with all the other AV cables, you still need a good ol’ pair of red/white RCA cables to also connect sound.Hope this helps!
How do I solder splice awg #6 wire to Amphenol (T) Ten-6 coax cable to use as a 1/2 wave dipole cb antenna?
I've tried a soldering gun@140 watts, but can't seem to get the awg#6 hot fast enough, to get the solder going. I would like to insert the braided (unbraided then hand twisted) coax outer mesh copper shield, and its center conductor, each into two separate awg#6 cable lengths (both halves of the dipole antenna), like a pencil into a sharpener. I keep getting cold welds though I've tried different types of solder and SP-30 paste flux. The soldering gun (140 watts) gets the wire hot but not enough it seems, though I can feel the heat traveling down the wire. How can I get this heavy gauge wire to accept the flux for a good splice (Electrical/Mechanical), before I melt or crystallize the insulator within the thinner coax cable? Would this give the best type of connection? Is awg#6 "too big" for use as a dipole antenna? Lastly, is there such a thing as a 5/8 wave homebrew dipole (horizontal) for use on both 10 and 11 meter band?
