Abstract:
Before the first Mercury encounter, the MVM'73 high gain antenna suddenly lost 3 dB in gain and changed from circular to linear in polarization. It was suspected that either particles or chips left in the S-band feed cavity after antenna assembly caused a short circuit, or a combination of tolerance build-up and thermal effects caused a dimensional change. Worst case analysis should be preformed on any equipment suspected to be sensitive to assembly practices or tolerance build-up.
