The Scientific Atlanta 12-1.7 is a standard gain horn antenna engineered for precise antenna gain determination via the substitution method on test ranges and in anechoic chambers. Operating across the 1.7 to 2.6 GHz band, this linearly polarized horn delivers 15.5 dB nominal gain with mid-band performance of 15.6 dBi. It serves as a calibrated gain standard and source antenna for experimental RF measurements in telecommunications and advanced test environments.
