26、with its counterpart. 3.2.6 Waveguide. The waveguide used with each adapter shall be of the type specified (see 3.1), and shall conform to MIL-DTL-85. 3.2.6.1 Positioning of the coaxial extension. The coaxial extension of each adapter shall be positioned on the waveguide so that all the electrical r

27、equirements are satisfied; however, since there are multiples of the satisfactory electrical lengths from the end plate which will also satisfy the requirements, the distance from the end plate to the coaxial extension shall be chosen as the shortest length possible. 3.2.7 Angular alignment. In asse

28、mbling flanges to a section of waveguide, 1 inch by .5 inch and larger sizes, the flange face shall make an angle of 90 degrees 30 minutes with the E- and H-plane of the internal surfaces of the waveguide; for smaller sizes, the flange face shall make an angle of 90 degrees 15 minutes. 3.2.8 Brazed
