What i'll like to know are the physical differences like focal point, curvature e.t.c.
What are the differences between ku band and c band antennas?
The C band at 4-8 GHz and the Ku band at 12-18GHz have about a 2.5:1 difference in wave length.
This results in antennae for the Ku band being able to create the same gain and beam with from a dish that is only 40% of the size of a C band antenna. The same physics applies to the antennas when it comes to focal length etc. Also if a mesh is used for the dish material it must have a 40% tighter weave for the Ku band.
Reply:Assuming you mean parabolic reflectors, they are intrinsically broadband devices, and there is no physical difference.
A number of parameters are related to wavelength, like beamwidth and antenna gain. These affect how you use the antenna, but do not affect the antenna itself.
