Antenna colinéaire

The antenna colinéaire is dedicated to the emission/reception of the omnidirectional type. Its profit, which depends certainly on the frequency, is proportional to its vertical dimension. The polarization emitted/received is vertical polarization. The antenna colinéaire can think like a Vilebrequin inserted in an envelope in the cylindrical shape of tube.

The antenna colinéaire 2,4 GHz ISM is used in the stations of reception Wifi. Its profit can reach 15 dBi, H: 2m. It is generally installed on a mast of antenna having the best immediate release, not of obstacle near of the same height.

The antenna omni-colinéaire can be built by the wifists and other amateurs, by respecting the dimensions, in coaxial cable 50 Ohms. The profit depends on the number of sections.
