Our thin-wall cast waveguide miter bends offer excellent predictable performance and are often used in applications intended for the space market. We hold a range of stock available for immediate shipment and custom designs can readily be manufactured on request.


Sylatech is highly experienced in the production of flanges and a range of plain, choke and double-ridged flanges are readily available in aluminium or brass. The machined precision design of these critical components offers excellent performance.

Flange sizes are available from WG10 to WG22 (WR284 to WR28) while couplings are available from WG8 (WR430) and custom designs can be fully accommodated.
