What the outside should look like when correctly mounted (poor quality camera phone shot in the rain).
Antenna extended. Note that it is significantly taller than OEM. Check your garage clearance to make sure you don't destroy your work... mine was close. I also had to do some overhanging tree-branch trimming in my driveway.
It also seems to take longer to extend and retract (9 seconds to be exact) but so far has been operating smoothly and reliably and radio reception is at least as good as OEM.
The electronic death stink in my car, on the other hand, is proving much harder to fix. If anybody has any proven suggestion for fixing that, I'd love to hear it! I have cleaned all the sheet metal with degreaser, and with vinegar, and have tried the usual baking-soda in a pan tricks, to no avail. I have also used commercial "odor eliminator" gel-pack and spray.
Currently I have disconnected my trunk light and am leaving my trunk open all day in nice weather hoping to air it out, but it seems to be a very slow process.
