    does carbon fibre panelling block radar signals. i am thinking about an application to use a module to detect metal sheeting at a distance from about 10cm to about 50cm from the face of the module, the device needs to be in a waterproof rugged enclosure such as a carbon fibre "box" or maybe fibreglass, ? , any thoughts .

    Hi Tom,

    Carbon is electrically conductive and you do not want this in your radome. You should use a material with low dielectric constant and low moisture absorption qualities. This page lists some materials with their rf characteristics: http://www.rfcafe.com/references/electrical/dielectric-constants-strengths.htm

    This article gives an overview of radomes:

    We made a non-waterproof example casing for the X2 module, see this resource.

    Hope this gets you started
