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. Paul _______________________________________________ RFI mailing list RFI@contesting.com http://lists.contesting.com/mailman/listinfo/rfi |
