Experimental measurements by wavepacket reflectometry are carried out to verify the low transmission loss of hybrid mode on HE{sub 11} in the corrugated waveguide with 88.9 mm in diameter. The HE{sub 11} mode is injected into the 62-m straight circular corrugated waveguide and the beat between the HE{sub 11} and HE{sub 21} (including degenerated TE{sub 01} and TM{sub 02}) modes is observed. The loss is too small to measure and inferred to be less than 2 db/km. The result shows that the use of HE{sub 11} mode for electron cyclotron heating system is suitable.
