WebIn digital circuits, a high impedance (also known as hi-Z, tri-stated, or floating) output is not being driven to any defined logic level by the output circuit. The signal is neither driven to a logical high nor low level; this third condition leads to the description "tri-stated". [1] Such a signal can be seen as an open circuit (or "floating ... WebSignal loss on 50 vs. 75 Ohm cable depends heavily on what radio frequency you're trying to transmit. At very high frequencies, certain 75 Ohm cables work better than 50 Ohm. However, for boosting cellular signal, the common 50 Ohm solutions (Wilson400, LMR®600, etc.) always provide better loss than a 75 Ohm cable such as an RG-6.Here is a guide to …
