[AFMUG] OT: Extending Garage Door Remote

[Nate Burke via Af]

I have a double steel garage door with Alumnium siding on the house.  
The Remote's have always been finicky since the opener/door was 
installed, but now I changed the lights in the Opener to LED Bulbs, and 
it's worse.  I have to be right under the opener to use the remote when 
the bulbs are lit (when they're off, it seems to work the same as it 
always has).  Seems that I may need to move/increase gain on the 
antenna.  Some things  I found online talk about running a RG59 cable to 
the outside, but then just soldering the original antenna wire on the 
end of it and just letting it hang outside.  Seems that there should be 
a better way.  Any suggestions?
