Refer to page 122 for details. ustomers requiring millimetric products fitted with anticocking flanges must request such flanges at the time of the initial enquiry. Purchase orders must specify anti-cocking flanges, if required, as such flanges can not be retro-fitted to products. NOT: nti-cocking flanges must be specified at time of order. Precision langes Precision flanges are fitted as standard to all lann calibration kit components and individual Metrology rade omponents. lann precision flanges are fully compatible with standard flange types. Precision flanges in the millimetric waveguide sizes also incorporate the anti-cocking feature. See from page 119 for details. Waveguide Materials lann is able to supply most products either in brass / copper waveguide or in aluminium. Metrology grade products have the waveguide sections machined to a high accuracy from solid material. The remaining products utilise premium drawn waveguide supplied to MIL specification or equivalent

12 nti-ocking langes reatly improved performance & repeatability ully compatible with standard MIL spec flanges The standard MIL spec style of flanges, normally used in the frequency bands from 26.0 to 220 z, are designs with the serious disadvantage that cocking can easily take place unless extreme care is taken when tightening the clamping screws. ocked flanges introduce high leakage levels and unnecessary discontinuities. In common with many other major manufacturers lann offers anti-cocking flanges, which prevent cocking when connected to similar anti-cocking flanges; these flanges are fully compatible with standard MIL spec designs. nti-cocking flanges must be specified at time of order. The lann anti-cocking flanges are detailed below etails of the W23 (WR22) & W24 (WR19) nti-cocking flange which is fully compatible with the standard U383/U style flange P M 0.3 /0.4 x oles 4 off UN-2. bore 3.56 dia x 1.6 deep from flange face oles 2 off /1.66 dia. sink 2.0 dia x 90 on front face oles 2 off - lignment pins 1.562/1.549 dia Note: owels & owel holes are precisely positioned with respect to the waveguide aperture after the flange has been fitted to the waveguide etails of the W25 (WR15) to W32 (WR3) nti-cocking flange which is fully compatible with the standard U385/U style flange P M 0.3 /0.4 x oles 4 off - rill 4.40 UN-2. bore 3.56 dia x 1.6 dia deep from flange face oles 2 off /1.66 dia. sink 2.0 dia x 90 on front face oles 2 off - lignment pins 1.562/1.549 dia Note: owels & owel holes are precisely positioned with respect to the waveguide aperture after the flange has been fitted to the waveguide.
