Radiometer SMG 40

....... 24 BNC barrels - I have loads of these already, all nice insulated-from-the-chassis types. I just need to get around to doing it. Indeed, I already have a 2U and a 3U version up in the attic, but these would take far too much space. They are called CTPs in the broadcast trade - Connector Termination Panels - and would be used at the rear of a bay for all the inputs and outputs to that particular bay.....

This raises the perenniial question of "to earth" or "not to earth". If all the connectors are earthed to chassis this can give earth loop troubles. Conversely not earthing them can give EMC issues. The outers of co-ax cables can be remarkably good antennae if not well grounded as they enter and exit bits of equipment.
