The HUB is a wearable Mini Base that expands the capacity of UltraLITE wireless headsets for larger crews that need to communicate and work with their hands.  This compact transceiver weighs only 9 oz and can either be placed strategically "on location" or belt worn. When clipped comfortably to the user's waist it moves seamlessly with your group allowing UltraLITE headsets to remain connected in full duplex. The HUB can be used as the seventh full duplex transceiver with addition of an Eartec plug-in headset.
