The Aerum Polar S antenna from TBS is a unipolar ultralight VTX antenna for miniquads and racing drones. It can be mounted using the included right angle aluminum bracket or using 3D printed mounts freely available for download. Reduced size and less weight, while still giving near-perfect omnidirectional reception.

Aerum Polar is a new style of PCB Antenna engineered in Germany for the car industry. Together with TBS the antennas were appropriated for the FPV market, since PCB technology makes it possible to design more reproducible and finer structures and to tighter tolerances. The FR4 material is resistant to impact and lightweight. The flat structure makes it nearly without air resistance when mounted in direction of flight!
