A bracket assembly is used to mount a wireless telemetry component proximate a rotating component of a combustion turbine engine (10), wherein the wireless telemetry component includes an RF transparent ceramic cover (128). The bracket assembly comprises a first mounting bracket (125) on a surface proximate the rotating component that includes a first (138) and second (139) bracket member spaced apart from one another. The first (138) and second (139) bracket members are disposed generally perpendicular to a direction of centrifugal forces generated by the rotating component. At least one of the first (138) or second bracket (139) members is inclined toward the other bracket member and disposed at an acute angle relative to the surface (141) proximate the rotating component.
