Details
Choose the BT-800S when you need a survey antenna built for RTK base stations and multi-constellation reception.
Designed for reliable field deployment, the antenna pairs a rugged dome housing with a standard survey mount interface.
Multi-band support, stable LNA gain, and a wide operating voltage range help maintain consistent positioning performance.
A 5/8"-11 UNC threaded mount and compact profile make installation straightforward on common survey poles and bases.
Coverage across major GNSS constellations supports more satellites in view for surveying, mapping, and RTK workflows.
The UV-resistant PC enclosure is intended for long-term outdoor use where sun and temperature changes are factors.
Low-noise amplification and flexible power input support clean signal reception across a range of field setups.
Connector and mounting details are designed around common survey hardware, with sealing features for outdoor installations.
Vehicle mounting supports applications like driving test systems and mobile data collection where consistent reception matters.
Cable length and connector combinations can be selected to match your receiver interface and installation distance.
