These are our most popular mounts! The mounting clamp can be positioned horizontally for horizontal mirror arms and rails, or vertically for vertical mirror arms or rails.  The clamp may be omitted which will allow the angle bracket to be used as a side bracket on any flat vertical surface, such as the side of a motor home or the back of a Jeep.  The brackets are made from cold rolled steel and are finished with chrome plating.  The K-6 does not include the antenna stud.  The K-64 is complete with our heavy-duty K-4 stud mount with ring terminal connections.  The K-64A model has our world famous K-4A stud mount with screw on coaxial termination.  All models come complete with mounting hardware.  The "64" and "64A" models are also available with stainless steel brackets and hardware.  Use one of the 3-Way Mounting Brackets for single or dual antenna installation on your car, truck, van, motorcycle or motor home.  The actual size of the bracket is 2.25" (57mm) wide by 2.9" (74mm) high.  With the stud in place, the height is 4.2" (107mm).  They protrude outward from the vertical surface 1.9" (48mm).  With the standard bolts supplied with the bracket, you can install it on a tube with a diameter up to 0.850" (22mm).  If longer bolts are used, the maximum tube diameter is 1.5" (38mm).
