FAQ

Q: What aluminum material do you recommend for horn antenna?

A: 6061 aluminum is the most common option with good machinability; 7075 aluminum is chosen for higher structural strength when needed.

Q: Can you do conductive coating on the waveguide surface?

A: Yes, silver plating or gold plating service is available to further improve electrical conductivity.

Q: How do you control the surface roughness inside the curved cavity?

A: We use fine ball end mills and optimized tool paths, then carry out manual or mechanical polishing for inner curved surface.

Q: What file format do you need for quotation?

A: STEP or IGES 3D model plus 2D drawing with tolerance notes is preferred.

Q: Can you modify the horn aperture and cavity length for different frequency bands?

A: Yes, we can fully adjust all geometry parameters according to your RF design requirements.
