After alot of research on digital in general and cable theory for digital transmission, I've decided to build a DIY digital cable using the following:
1. 5ft, Belden Part# 1694A RG-6 coaxial cable
2. 2ea, Amphenol BNC connectors, Part# 31-70000
I'm going with an appoximately 1.5 meter length based on general consensus and info that this length seems to be optimal for digital coax, to reduce impeadence mis-match reflections. The Belden 1694A is top-rated, and specifications are the best to be found for 75ohm RG-6 cable. It has a copper, solid core center conductor (I don't like silver). The Amphenol connectors are the best in the biz, period.
Everything will be crimped (no solder).
I'll post pics/instructions when the parts arrive in case anyone else wants to give it a go...
