Bnc Patch
I would like to make my own bnc video patch cables. What is a good quality cable to use?
I would like to make my own video patch cables to use in a portable rack mounted road case. Standard off-the-shelf ones don't last so I would like to use a cable that is very flexible.
I'd also like to make up some 'Y' adapter cables to avoid using the BNC solid Y adapters that put more stress on the panel mounted BNC sockets.
What is a good quality cable and what are the matching BNC connectors that go with it?
Is solder better than crimp? I'm a pretty good solderer and when I'm on the road I'd prefer not to have to carry an extra crimping tool.
The impedance is very important to video signals. It's not a good idea to split, T, or Y a video signal unless you can turn off the termination and daisy chain the signal, leaving the termination only at the end. Trying to connect 2 coax cables into one BNC connector simply wouldn't work. Getting the 2 center conductors into 1 pin would be a real challenge to say nothing of trying to put the 2 cables into the the back of the connector.
You can certainly build your own jumper cables. While RG6 has lower loss, RG59 is a stronger cable. For short jumpers the difference in loss won't be a factor and the cables should last longer. At 200 MHz there's only about 2 dB difference in loss in 100 meters (328 feet). Use a cable with a full braid as well as a foil shield. The full braid adds to the mechanical strength of the cable, especially where it's connected to the BNC. I prefer the soldered center pin and clamped shield style of connector. When done correctly they last longer.
