I think this video sums it up right here, https://www.youtube.com/watch?v=Sq3zEpYgCYo This leads me to wonder though, Why do so many UHF radios come with SO-239 sockets for antenna use rather than BNC or N connectors? It even seems that newer UHF radios still use the SO-239. Another question I have is weather or not someone should consider having the SO-239 changed out for the N type connectors? Would there be some form of improvement or has some form of compensation been made on the PC board in those radios?
