We carry out 100-GHz band test observations with the newly-constructed KVN 21-m radio telescopes in order to evaluate their performance. The three telescopes have similar performance parameters. The pointing accuracies are about 4″rms for the entire sky. The main beam sizes are about 30″(FWHMs), which is nearly the diffraction limit of the telescopes at the observing frequency (97 GHz). The measured aperture and main-beam effciencies are about 52% and 46%, respectively, for all three telescopes. The estimated moon effciency is ∼84% for the KVN Tamna telescope. The first sidelobes appear 50″(∼1.6×FWHM) from the main beam centers and the levels are on average -14 dB.
