VAS Avenger XR18 5.8GHz - 270mm RHCP SMA

VAS Avenger XR18 is a directional antenna with right-hand circular polarization RHCP, an SMA connector and a gain of 18dBic for the 5200-6400MHz band. It is the most powerful model in the Avenger series, intended for the receiving side in long-range flying. It is based on the patented Crosshair Xtreme antenna technology, which VAS enhanced with a parasitic waveguide (“parasitic waveguide”) — this increased not only the gain, but also the axial ratio to 0.99. A high axial ratio means very pure circular polarization, thanks to which the antenna more effectively suppresses reflections and opposite-polarity signals.

The high gain is paid for with a narrow radiation pattern. The beamwidth is 32°, with a -3dB drop already at ±10° off axis. The antenna therefore must be pointed at the model and is not suitable as the only receiver antenna. The manufacturer recommends combining it on a diversity receiver with an omnidirectional antenna, such as the VAS Ion Pro or Victory. The directional antenna provides range and signal penetration through trees and buildings, while the omnidirectional one covers the near area, takeoffs and landings.

The antenna is 270mm long and weighs 106g. It is mounted with an M4x0.7 threaded screw, so it is suitable for a tripod, ground station or separate mount. The antenna housing is 3D printed, so minor surface imperfections are normal and do not affect function.

Video Aerial Systems (VAS) is an American company focused on antenna development and production. It holds several of its own patents and its antennas are among the very best.

Important notice: due to its size and weight, we do not recommend mounting the antenna directly on FPV goggles.
