section of 3" x lA" waveguide for use over the range from 2600 to 3950 mc. This instrument differs from all of the above sections in that it is provided with its own carriage assembly and can not be used wich the Model 809B carriage assembly described above. However, the S810A does use either of the two probes described before.

flanges

All -bp- waveguide equipment is provided with plain cover flanges. For applications requiring choke flanges, the Model 280A cover-to-choke flange adapters are available in each size of waveguide, equipment resume'

A tabulation of the complete line of waveguide equipment is given on the back page of this issue.

Acknowledgment is due Mr. R. M. Kingman of the -bp- Mechanical Design Department for his valuable contributions toward the development of the instruments designed under the program and particularly toward the development of the slotted line equipment. Acknowledgment is also due Mr, Arthur Fong for the development of the 806B coaxial section.
