Active Dual Circularly Polarized GNSS Antenna (DCP GNSSA)

The DCP GNSSA is an active antenna for positioning, surveying and navigation that receives both the RHCP and LHCP signals simultaneously and with a high isolation.
It covers all GNSS frequencies in L band, shows excellent performance in open-sky environments and clearly detects signals which have been corrupted by diffraction and reflections. The antenna can also be mounted in a customer-specific housing.
