Ground Dependent MountingThis GME antenna needs a large uniform metal surface beneath the radiating elements to perform correctly. This is referred to as a ‘ground plane’. Therefore the best position to install an antenna is in the centre of a metal roof, however, this is not always possible and installation on a bull bar or mirror mount is often necessary. In this case a ‘ground independent’ antenna should be used to give the antenna its desired radiating pattern without a metal ground plane.
