This antenna was engineered from the "[http://df.mchobby.be/ballon-meteo/cheapyagy.pdf Cheap Yagy]" (''pdf''), issue from the "[http://www.wa5vjb.com/yagi-pdf/cheapyagi.pdf Controlled Impedance 'Cheap' Antennas]" article written by Kent Britain WASVJB.

A simple rule of three can be used to adapt the antenna to other frequencies (the antenna was already adapted from a 432 Mhz design).

From a deeper read of the [https://arduino103.blogspot.com/2018/08/ballons-meteorologiques-tout-savoir-sur.html QSO magazines series], we learned that 6 elements Yagi can offer a gain up to 11.2 dBi.

It seems that the 11 elements Yagi ([http://df.mchobby.be/ballon-meteo/cheapyagy.pdf see original document]) '''will double the gain'''. Whoaw!!!
