ALMA MEMO #444

Recommendations for Flat and Anti-Cocking Waveguide Flanges

A. R. Kerr, L. Kozul and A. A. Marshall

2003/01/06

As discussed in ALMA Memo 278, flat and anti-cocking waveguide flanges are preferred over the common Mil-F-3922/67B (UG-387
and -383) type of flange with its central boss. While flat and anti-cocking flanges are in many ways similar to the /67B flange,
there are important differences in drilling, counterboring, and pin insertion details if these flanges are to be compatible with one
another and with the /67B standard.
