At last a troubleshooter's ferrite kit that works from 150 KHz to 2 H=GHZ. Now you can suppress RFi from unknown frequency ranges with a full spectrum of ferrite cores that have a 1/2" ID large enough for multiple turns of many common data and signal wires. Try 1 mix and see if it has an effect and if not then try another until you suppress the unknown frequencies. Or use them all to provide protection across a broad frequency range. 3 ferrite cores provide at least 500 ohms in the frequency band to give a measurable difference in RFI and noise suppression.
Square or Hex sided depending upon inventory stock

Christmas lights or yard lights with switching DC power supplies are often the RFI source and a clamp on ferrite bead on the AC AND the DC side feeding the lights is needed to help suppress the switching power supply RFI noise. Suitable snap on beads are FSB31-1/2 for the 1-250 MHz range.
We have also had reported wireless HDTV boxes, and FOSCAM and AMCREST security camera systems causing RFI to garage door remote openers. Use our Garage Door Opener RFI kit to suppress the interference to the opener (VICTIM) – you need one kit for each opener. Maximize the distance from the camera to the openers may also help. Additionally shield cable to the garage door sensors may be needed depending on severity of the camera RFI.
Obvious Tech Note: make sure your remote batteries have enough energy to activate the GDO or the signal they transmit may not be large enough to over ride the RFI signal, but a fresh battery may be able to overcome the weak RFI source and allow the GDO to operate correctly.
