FAQ
What is TCA920 used for?
TCA920 is used for surveying, reference stations, monitoring, machine control and other applications that require stable GNSS signal reception.
Why use a choke ring antenna for reference station work?
A choke ring antenna helps suppress multipath effects, which is important for fixed reference stations and high-precision positioning networks.
Which TOKNAV receivers can be paired with TCA920?
TCA920 can be positioned with CORS/reference station receivers such as NET660, NET660i and tBase depending on project design.
What installation details should buyers confirm?
Confirm receiver model, mounting environment, surrounding obstructions, cable plan, required signals and target accuracy before final antenna selection.
