With whom do you put the most faith to report your are down? In Canada all aircraft are required to monitor 121.5 so a vertically oriented antannae would offer the best signal strength to an aircraft complying with the law. But, here in the USA and most other parts of the world, there is no requirement to monitor 121.5. My ELT antannae is mounted horizontally for maximum satellight reception!
