Review on Metra 44 UL10 Universal Locking Retractable by Matt Bokil
Fits up to 1 " hole
Although I've installed it on my car I haven't installed the radio yet so I don't know how good/bad this antenna is .But it will not fit a hole larger than 1 inch
Pros
- Universal retractable antenna specific to Mazda RX7 cars
Cons
- Almost never
