Review on Firestik K-11 Magnet Mount with 18-foot Coaxial Cable by Adam Matthews

When I received the product it only fit a 3ft high antenna. Of course the 5ft Firestik2 fell off after 3 minutes of driving. As with any magnet, the holding power of the attraction depends on the thickness of the sheet metal. You can attach a thicker piece of steel to the surface of the car to give it better holding power. Hitting the stick too hard will bend the metal top of the magnet where the hole is, resulting in a bad connection.
