    I have a 10 year old Chamberlain and the range sucked - from every source. I did exactly as you are thinking and soldered a long thin (~20 gauge) wire onto the short one hanging out of the unit. To get it outside my metal garage door that was likely attenuating some of the signal, I ran that wire out through a tiny hole in the garage door trim and ran it vertically from top to bottom on one edge then painted it in. It tripled my range and works >90% of the time with the default geofenced Tesla settings.

    We have two openers, one a overhead door and one craftsman. The ohd opens from 4-5 houses away the craftsman I have to be sitting in the driveway.

    I went with technology and got a myq for both doors for $68 at Sam's club. Now I can open and close from anywhere and it will alert me if I forget to close and even autoclose at set times. Lengthening the antenna doesn't help if the opener signal is not getting through the door/wall

    This is exactly what I plan and doing and hope it works!

    Does the type of wire used to extend the antenna make a difference?

    Should I get standard copper wire or would "tinned copper" wire work just the same?

    As long as the wire is copper it will work. Do not use copper plated steel. The only thing better than copper would be pure silver wire. That would be an expensive antenna extension.

    Turn off everything that is within 50 feet of the opener and try again. You may not need an antenna extension, just an appliance replacement.

    I installed a new Chamberlain opener that is on 390 MHz (yellow antenna wire insulation) to replace a Craftsman opener from 1977. The car can now open the door from the street which is 75 feet from the garage and I have steel garage doors.

    Before making any changes - would recommend first testing using a remote supplied with the opener. If the range is acceptable for the handheld remote, then the problem could be with the homelink hardware in the car.

    While longer range is useful - a downside is that you can get unintended openings from the car. If you have the trigger point set in the car on or close to the street, if you drive by the front of your house, the software could trigger the opener - and you could end up leaving the house with the garage door open.

    Be careful on the off brands. This is something I wouldn't want to take a chance on. I did the Genie brand, and well, at least they make the openers themselves.

    Some of you are making a 'random wire antenna'.

    The length of any antenna is a function of the frequency it's supposed to work at, and the speed radio waves travel through the copper. For best efficiency and to reduce standing waves, make it 1/4 wave, 1/2 wave, 1 or some multiple. Here's a calculator: Wavelength Calculator K7TJO

    Gauge of wire does matter. Too small increases impedance. 18 gauge is fine for a longer antenna like this.

    Does the optimal length different based on wire gauge?

    I thought finding 30 feet of quality 18-guage copper wire would be so easy on Amazon. Apparently not. Just about everything they sell is tin and copper. Anyone have a source for quality copper cables?

    Also I found this guide handy for figuring out the frequency:
    garage door openers learn buttons color difference

    With my purple button, the frequency is 315 MHz and therefore the length should optimally be a multiple of 37.47 inches or 1/4 or 1/2 of that.

    He should caulk the hole in the wall, so more bugs do not come in the garage.
