I was going to try that today. And I did. And it solved my problem. Can hit from the street.I extended the antenna on my garage door opener by about 9” and now I have great range.
Interesting … may need to give these a try. I have a Sommer Direct Drive/Synoris system and there doesn’t appear to be a wire that I can extend for better range (at least that I can find on first glance).Another issue could be if you're using LED bulbs in your opener. My reception was terrible, but then installed low interference LED bulbs (found some on Amazon), and reception improved dramatically.
