The original antenna obtained with the ADS-B receiver AirNav( RadarBoxPRO is so great product that it is hard to build a better home made omnidirectional antenna with a higher gain than the original one. During my almost one year period of experiments with various types of antennas I built only one which fulfilled this expectation - it is the coaxial collinear antenna... Antenna is used in the vertical position due to the polarization of the ADS-B signal... Coaxial collinear (COCO) antenna for the ADS-B receiver. Construction, protection against lightning and static electricity and results of the tests are described in this report. Significant improvement of the polarogram was achieved.
