Abstract:

A pocket size antenna match indicator is described having a self contained modulated low level RF signal source which is applied to an antenna or other load under test through a dual directional coupler. Sampled RF reflected signals are detected, filtered and amplified to provide a DC voltage directly proportional to antenna mismatch. Easy to read measurement of VSWR is derived from the DC voltage by means of a dot display driver connected to a LED display. Author
