You are correct about HD-SDI being unlike CVBS. And, yes, fewer connections = better signal. Most of the BNC adapters on the market are not true 75-ohm. I have almost never seen T's or L's that are 75-ohm. Look in the end of the female BNC...if the little tubular pin is supported all the way up with a piece of plastic, it's not 75-ohm. Connectors and adapters that are not true 75-ohm will cause loss in a HD-SDI signal stream. And, once it gets data losses...it's gone.
