LRB
Palm-size external radio with internal battery, 10–20 km range and wireless connection.
LRB is a compact external radio for GNSS base stations. With 7 W output and STEC's S LINK Ultra protocol it reaches 10–20 km. A 13,600 mAh internal battery gives about 2 hours of operation, and a regular Type-C power bank extends that to around 10 hours, so no heavy car battery is needed. It links to the base receiver over Wi-Fi or Bluetooth, is set up from a web interface, and supports NTRIP through a SIM card.
