Low Deformation Large Aperture Antenna Support Base

Fine Tolerance Reflector Support Structure | SKTC Lightweight Dual Reflector Space Antenna Base Product Overview Aerospace satcom subsystem developers and RF payload procurement teams understand that the mechanical backbone of a Cassegrain antenna directly determines its far-field RF performance. Even minor relative offset between primary and secondary reflectors triggered by thermal gradients or launch dynamic stress will distort the feed wavefront, suppress antenna gain and raise unwanted sidelobe levels over on-orbit service life. This Fine Tolerance Reflector Support Structure is the custom SKTC engineered base built for paired dual reflector antenna systems. It is designed to carry a 2 m primary reflector with surface accuracy controlled to RMS 0.14, alongside a 1 m secondary reflector held at RMS 0.10. Manufactured from low-CTE, stress-relieved lightweight alloy and validated with CMM metrology, this assembly preserves critical focal geometry and angular alignment through vacuum…
