How to Install a Shorty Antenna on an Aston Martin V8 Vantage
This is the quickest and easiest modification you can do to an '06-07 Aston Martin V8 Vantage. All you need to do is twist off the original antenna (lefty-loosey), and then twist on the shorty antenna (righty-tighty).
About a minute
Remove the old antenna by twisting it loose.
If the threaded adapter supplied with the new antenna isn't already in it, thread it into the antenna. Install the new antenna by inserting it in the place of the old one.
So. Frickin. Easy.
