Description

Calibrated by NGS Survey Quadband (L1/L2/L5/L6) 3D Choke Ring GNSS antenna. Water & dust-proof for permanent outdoor installations. Sub-millimeter phase center repeatability.
Ideal for reference stations (CORS), base station, geodetic survey, deformation monitoring, earthquake forecast, but also for fixed installations supporting L-band.

Good to know:
– Compatible with all simpleRTK3B boards as well as any other multiband GNSS receiver in the market
– Bulk pricing starting 50 units
– This product is a cheaper alternative to Trimble Ti-V2, Novatel GNSS-750 or Leica AR20 Choke Ring antennas

Includes:
– 3D Choke Ring GNSS Tripleband + L-band antenna (IP67)
– 1.5m pigtail cable with TNC to SMA connector
– 2.5m pigtail cable with TNC to TNC connector
