We put our 5' dishes 40' apart - worked really well. Then we installed a temporary exhibition with metal signage panels directly between them I.e. removed the line of sight. They still worked almost as well! Presumably the sound travelled over the top of the panels and was then focussed. (?)

>> Hi, guys. Does anyone know if there is an intrinsic limit on how far apart whisper dishes can be? Would they work at a separation of 100 feet? And if they are farther apart, does that mean that the dishes need to be bigger? Many thanks,
