LED bulbs product 300 to 400 mhz radio signals that interfere with garage door opener signals. need to get receiving antenna away from the lights. I too live in a steel building. I had to use grounded coax cable extended to the outside of the building. I stripped away 9" of grounded exterior cable, mounted through insulated bracket not allowing the center 9" wire to touch ground. Use aluminum tape on antenna wire that is not covered by ground inside the building. solder connections. Antenna length is determined by wave length, only need 1/4 wave. Grounded exterior of the coax cable is what does the trick.

Thanks for posting this! I have a metal garage door and metal roof insulation and my car's homelink has trouble communicating even in my own driveway! I'm definitely going to give this a shot. What kind of bracket did you use to keep the antenna oriented upright?

You have become your parent--you need a Dr. Rick intervention...just like in the Progressive Insurance commercials

Great content! You have my dream home!

[@monkeybusiness2221]

It definitely took a lot of work but I am super happy with it!

Thats i nice building you have! I have a similar setup, also the lift master 8500. How long do you make the antenna? Maybe you mentioned that, isn’t the length of the antenna critical for the frequency? I’m not an expert and would like to know from someone who has expertise in radio operation.

The Wind may have been blowing in the wrong direction.

I'm having the same issue with my opener not having enough range. Can you tell me what the rod for the antenna you purchased is called and where can i buy it from?

[@monkeybusiness2221]

I used copper coated welding filler rod from harbor freight. Then soldered wire too it. You can purchase that at any welding supply place

Sooo you say “uuhhh” 45 times in the first 4 minutes of your video. That’s once every 5 seconds. If you’re gunna produce more content, you’ll want to be more conscious of that. Not that I’m a professional or anything.. just saying.

[@monkeybusiness2221]

Yeah I have always had that crutch. I appreciate the constructive criticism, and im working on it.

I counted 47, I thought it was 48 but upon playback it was an "uh" not an "ah"
