Garage Door Opener RFI Kit

Home Theater/Audiophile RFI Kit

The Home Theater RFI Kits are specifically designed to cure most home theater systems triggered by Radio Frequency Interference problems from AM, FM, CB and Ham radio stations. The kits contain ferrite toroids (“Ring” shaped) for the AC power cord protection and “Snap on” ferrite beads for HDMI, audio, video and speaker cables. The ferrites are selected to eliminate RFI from 1 to 1000 MHz. The ferrites are easy to install, don’t require modification of the protected equipment and work in almost all cases to suppress annoying interference issues.

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.
