Two different gain measurement methods based on use of a VNA and two power meters are applied for precision high-gain measurements of CFRP spacecraft reflector antennas operating in Ka-, Q/V-bands. The test setup installed in a Compensated Compact Test Range applies harmonic mixers, diplexers and a reference cable to allow efficient ‘One Cable Measurements’ including rotary joints.
