[time-nuts] Leakage, tinySA

[Mark Spencer]

I use RG400 for most of my time nuts activities.   When I switched from cheap RG58 style coax to RG400 a number of strange issues seemed to go away for me.   

Your mileage may vary (:

Mostly I use RG316 cables on the bench. For more than a meter or so I go with RG400. You can get either type of cable terminated with N, BNC, TNC, or SMA connectors.
