This RFI kit was created to suppress RFI issues with your cable tv box interference. This kit was created out of necessity from a ham using high power antennas near the cable TV box. The use of the ferrite filters completely eliminated the RFI issue allowing the ham to enjoy the use of the cable TV system while using the ham radio system.
The ferrite filters are selected to suppress RFI from 1 to 300 MHz. The filters are easy to install, don’t require modification of the protected equipment and work in almost all cases. See product picture for suggested filter use.
What is included in the kit?
The RFI-CABLETV kit contains a snap on filter for the AC power cord, the HDMI/Video output cable and the and coax cable TV input cable.
You get three 1/2" ID snap on RFI filters and an installation manual.
You need 1 RFI-CABLETV RFI kit for each cable TV box afflicted with RFI.
For additional protection of the video monitor use the RFI-HDTV RFI kit which suppresses RFI coming into the AC power line into the HDTV.

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.
