Elliptical waveguide is often used in microwave antenna feeder systems, and offers benefits like low loss and signal distortion. Elliptical waveguide also ensures VSWR performance. Elliptical waveguide is precision formed from corrugated high-conductivity copper with an elliptical cross-section component. It is this corrugated wall structure that in turn gives the waveguide high crush strength, lighter weight, and better flexibility for handling. Contact Tessco with any questions, but we offer a full range of waveguide sizes for your applications from 1.7 to 26.5 GHz.
