Has anyone followed the lines of Spectre's making a larger external horn and made a larger horn for greater sensitivity for their RD? Not the spectrum analyzer posted last month, but something small and capable of being clipped onto the front of an RD. I've got a few inches in front of my V1 and the extra sensitivity could be useful vs I/O if something could be designed to look further down the road. I'm still doing research on antenna theory in that range and was curious if anyone had ventured in that direction. And if it's something that innocently sits in front of the device then it's not messing with any FCC regs either.
