This is Hollyland's official replacement antenna for the Solidcom Roaming Hub, part number HL-HATN02, sold as a single antenna. The Roaming Hub is the network node used in Hollyland's Solidcom C1 Pro Roaming Version wireless intercom system, which lets crew members wearing Solidcom headsets move between the coverage areas of several hubs without losing their full-duplex talk connection. Hollyland quotes a transmission range of up to 500 m for the C1 Pro system, and range and reliability depend on the hub's antennas being fitted and undamaged, so a spare antenna is a sensible item to carry in a broadcast, church, sports or live-event intercom kit. The antenna is a black, straight rod-style design with a knurled metal connector at the base that screws onto the hub's antenna port. It is a like-for-like spare for lost, bent or broken antennas on the Roaming Hub and is a different part from the paired antennas used on the standard Solidcom C1 and C1 Pro HUB base station, which Hollyland sells separately. Supplied as one antenna; the hub itself is not included.
