How to determine spacing on parabolic grid antenna?

[CosmicVoyager]

Greetings,

How far apart should the wires be on a 2.4 GHz parabolic grid antenna?

Is it determined by the frequency?

Thanks

hi there,

1/10 wavelength is the max preferred. yes it is determined by frequency. ie the higher the freq the smaller the maximum gap between the grids.

so for any given freq you could have a solid reflector up to a spacing of 1/10 wavelength. On 2.4 GHz a max of ~ 2cm would be the norm.

cheers
