Solution for Weak HomeLink Performance

I posted this comment in another thread, but felt that it could use some more exposure:

My Magnum EVIC HomeLink (despite the dealer replacing it once) did not have the range of my 300M, nor the hand-held remotes. I solved it by lengthening the garage door operator antenna by a fractional wavelength. That is to say I doubled the length of the OEM opener antenna.

All you need to do is:

1. Get a piece of 18-22 gage (not important) wire exactly as long as the existing antenna (you will have to guess the length in some cases when the wire disappears into the housing).

2. Use a butt connector to join the stripped ends of the existing wire and the new one.

3. Let it hang down from the opener.

Now the Magnum hits the opener from a reasonable range and the others can hit it from about 100m away!

Yeah, I've noticed my HomeLink was weak. This is good info.

Before I could hit the garage door open down the street. Now, even at the end of my driveway it doesn't work (my driveway is fairly long). I almost have to be right on top of it to open.

Wasn't a big hassle, but it did take getting used to (and I have to remove to close it sooner rather than later now too).
I have many trees, etc. in the way, so perhaps that affects it. But even holding it down doesn't make a difference. I have to be within a few car lengths of the door for it to respond well.

I'm planning to lengthen my antenna this weekend sometime and see if that helps.
