Making One's Own RGB cables

Hello Assembler folks. I'm not entirely sure if this is the correct section but it seemed most relevent to the question I'm about to ask. I would like some information on making ones own RGB cables. I have a lot of experience making audio cables and have a ton of supply sources for that end of it (used to work in a recording studio), but I have no experience in making video cables aside from standard RCA and coax tv cable. Im going to give a specific example and hopefully I can use the answers given for more general applications.

Say I wanted to make some RGB cables for a Genesis 2. The terminations are the proper DIN connector on the Sega side, and 4 male BNCs (RGBs) for video (disregard audio as I am well versed in that). If I was to construct cables in this manner, what would be the absolute best quality cable to use for video signal transmission that could work with the given terminations? What gauge, type of sheilding, crimp or solder? Also, for neatness sake, does anyone know of a source for outer sleeving? I am aware of the resistors and caps required for proper signal, but right now I'm only interested in the cable part. Can anybody weigh in on this? I see a lot of crappy made cables out there, and all the better quality ones seem to be SCART only, but I am not interested in modifying premade cables as I would like to be able to dictate lengths for neat permanent installations.

Thank you for your link, but that site is more or less just pinouts and is centered around SCART connections while I was asking about construction materials and is based around BNC.

 

ah I didn't read your post properly

I do CCTV and use waterproof compression connectors, using a compression tool (not the hex crimp). Best cable to use would be same as CCTV systems as they are also TV systems, do not get the aluminium cable but better the copper screened cable, which not only is superior but also the screened will stop interference

as for BNC is pretty much the same concept as the link so you can use to fashion BNC Component RGB cables

 

I made mine using bulk VGA cable from a home theatre supply store. This gives you a sturdy shielded cable with three colour-coded mini-coax cables (for your red, green, blue) and a decent number of single-core wires for sync signals and whatever else strikes your fancy.

The individual coax leads are small, RG-179 or RG-180, because the signals are low frequency, low bandwidth, so you don't need whopping RF-grade co-ax to get a clear picture. (Even up at 1600x1200, which is what these cables are designed to handle)

 

Agree - vga cables are good. Decent cables are shielded well, as VGA was analog and no one likes a shitty picture on a monitor.

 

I am not very good at soldering but ended up putting some RCA jacks on my Model 1. I knew in the end if i tried to make a cable it would look like ass.

I am in the USA and using a Sony PVM so I don't necessarily need SCART. I soldered some wire's from the pinouts on the Genesis circuitboard to the solder points on the RCA jacks. Red, Green Blue and composite for sync. Using some BNC->RCA adapters I can just use a standard COmponent YPbPr cable with RCA on each end to go between the two, and seems to work just as well as the fancy SCART cables I bought.

Hope this helps
