In this paper, the effect of distributed loss loading and guiding center radius modifying on the stability of a TE11 mode Gyro-Traveling Wave Tube (Gyro-TWT) is studied by multimode steady-state method. The result shows that the output power of the backward oscillation mode keeps weaken till zero as the conductance of the lossy material reduces, while the output power of the working mode grows significantly. As guiding center radius increases, loss loading needed to suppress oscillation completely is weaker, which makes heat easier to dissipate. Besides, the increment of guiding center radius also makes the output characteristic less sensitive to conductance variation.
