This page shows the reliability and performance of UltraBeam antennas under what we normally understand as extreme climatic conditions. Particularly significant is a particular weather condition that has generated severe wind and ice simultaneously.The antenna is the 4-element yagi 6-40 metres. It is worthy to remind that the 3 full-size 40-metre elements are 21,7 meter long. The actual size and wind-area of this antenna model give a better idea in relation to electrical and mechanical performances of the antenna. UltraBeam warmly thanks our friend and OM Zdenek Vesely, OK2DA, for providing us his significant testimony supported by a photographic documentation of the event.
