Abstract:

A two channel, predetection diversity combiner is described. The combiner uses two commercial telemetry receivers as a basis the necessary subchasses were constructed to 1 combine the expected signal from two antennas to improve the signal-to-noise ratio and 2 measure the relative phase of the signals at the two antennas. Photographs demonstrate the improved signal-tonoise ratio of the system.
