SIRIO CRUIZER is marine (156-163 MHz) antenna designed to work without counterpoises. It is extemely protected against the most severe sea conditions, due to the fibre glass whip, which makes the antenna tough and robust withstanding every weather conditions. The whip is DC grounded in order to avoid RF stray currents and static discharges. All metallic parts are made of chromed brass. Antenna package comes complete with marine bracket "M8-NY" and white color coax cable RG-58C/U. In working frequency band there is no need of SWR tuning.
