Mini Choke Ring Antenna

V3N-GGI-105 is the ideal antenna for a wide range of high accuracy permanent, reference base station and monitoring application.

The V3N-GGI-105 contains V3novus advanced antenna technology for improved tracking performance, excellent phase centre symmetry and unmatched multipath suppression across all GNSS frequency bands. An all new amplifer (LNA) is used to provide excellent out of the band rejection, helping to significantly reduce potential interference due to jamming. The V3N-GGI- 105 is suitable for use with antenna cable lengths up to 100m without the need for an in line amplifier.

The V3N-GGI-105 contains new innovative internal structure design, robust and UV resistant radome, it's made to withstand extreme temperature, humidity, dust, salt, solar radiation, shock and vibration with in very small size.
