11、also available. We are also able to supply special flanges to customers requirements.Standard FlangesAll waveguide products in this catalogue are tted with Flann “Standard Flanges” as listed on page 108, except where stated.Note: Choke flanges are not recommended for broadband waveguide equipment.De

13、r Millimetric Waveguide Bands Greatly improved performance and repeatability Fully compatible with standard “Mil spec” flangesThe Millimetric flanges in the Series UG-381/U to UG-387/U are notorious for “cocking” during connection which results in leakage, increased insertion loss, discontinuity and
14、 poor repeatability. Flann produces a range of millimetric “Anti-cocking” flanges which provide greatly improved performance and repeatability whilst maintaining full compatibility with standard Mil spec flanges. “Anti-cocking” flanges are optionally available on most millimetric products in the Fla
15、nn product range. Refer to page 119 for details. Customers requiring millimetric products tted with anti-cocking 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-tted to products.NOT
16、E: Anti-cocking flanges must be specied at time of order.Precision FlangesPrecision flanges are tted as standard to all Flann calibration kit components and individual Metrology Grade Components. Flann precision flanges are fully compatible with “standard” flange types. Precision flanges in the millimetric waveguide sizes also incorporate the “anti-cocking” feature.
