Re: Drip Dual-STA 5167 Limiter

The reason why some SMA cables are very expensive is the RF use (transmitting) with rated cables. According to Drip you don't need these and you may use the cheep ones. Personally I think SMA is a good thing for must be shielded signal applications - but why use it for uncritical connections ? Like the IDC's better there. And maybe it's nonsense, but I don't use it for high power (heater) and high voltage connections unless I know the rating of the cables - that's the expensive ones.

Makes sense.  I will have to go double check which connections are which (diy has slowed down for me since the holidays), but I suppose the main thing I’ll look out for are the high power/voltage connections, and invest a little more money into appropriately rated cables there, and use the cheapo cables for the other ones.  It does seem reasonable to at least know the rating of the cables in those important spots, even if it turns out (for example) that all SMA cables clear the necessary ratings by default.
