Measurements were made of electromagnetic propagation in a coaxial electrode structure filled with longitudinally magnetized plasma. The annular plasma region had a 9.55 cm outer diameter, a 3.82 cm inner diameter and was approximately 60 cm long. A magnetic field of 300 gauss was employed. Electromagnetic wave frequencies were in the range 0.5 to 2.4 GHz. The plasma was generated by a continuous glow discharge. The resulting Ω vs. β curves closely follow the predicted curves for the ''quasi-TEM'' mode. On the basis of this model, plasma frequencies were 40--80 percent of the cyclotron frequency, depending on magnitude of the glow discharge current.
