The Ion Pro is the latest improvement to the VAS Ion series antennas incorporating a more sophisticated element system for a high axial ratio omni-directional signal.  Not only is the gain the highest of any single CP omni at a true 2.5dbic offering longer range, the refined circular pattern of the antenna allows pilots to operate in the most difficult RF environments such as urban areas and race courses.  Designed to be used as both a transmitter and a receiver antenna, the Ion Pro is the perfect choice for professional pilots who need to get their signal where other antennas simply can’t.  Each antenna is tested not only for SWR, but also for radiation pattern and axial ratio during the manufacturing process to ensure that every antenna performs to the highest standard.
