Just a few quick photos of the 22″ parabolic reflector with ultrasonic transducer I built yesterday for locating arcing RFI sources. ~ 73 from KK4ICE
New Parabolic Reflector Built for Ultrasonic RFI Source Chasing
Category: RFI Elimination
220 Mhz, 6-Element Beam Antenna
I built this handheld 220Mhz, 6-Element beam yesterday. It’s constructed of a 48″x1/2″x1-1/2″ strip of Poplar, six silicon bronze welding rods, and a piece of coax robbed from an old, broken mobile antenna mount. The PVC handle added to the end is simply to make it easier to hand-hold. Initial testing of the antenna brought […]
Ultrasonic RFI Detector Pinpoints Possible Faulty Lightning Diverter
After devising a way to accurately sight the parabolic reflector I’m using in my ultrasonic RFI source locator, I went back out to the suspect pole today. From three different vantage points, the system zeroed in on the device highlighted in the photos seen below. The device appears to be a lightning arrester/surge diverter. I’m […]
Ultrasonic Detector for Locating RFI Sources on Power Poles Completed and Put To Work
First actual use of the ultrasonic system I just put together for hunting down RFI sources on utility poles. Narrowed it down to the top of this pole. Definitely some arcing going on in a connection, insulator, or other hardware at the top of this pole: Here is the Son-Tector Ultrosonic Probe Kit which […]
