I would like to see the photo of an ultrasonic RFI locator with 19"
dish. I would also like to know where you got the dish. I have a 12"
one and have thought about trying to go larger. The problem is
finding a dish that is flat enough. The available 40 kHz transducers
have about 50 degree directivity. That requires a very flat dish. I
haven't been able to find any suitable candidates.
