This invention relates to a gear mounting having a spindle extending substantially normal to a carrier and capable of radial excursions from an initial position, when under load. The conductor is connected to the soldering portion by melting the solid solder held in the holding portion. The arm cradle can be pivoted relative to the handle about a pivot axis that is offset to either the left or right side of the handle. In this manner, the acquisition range of the radar system is optimized.
