Rapid exchange system for testing wireless networks

A method of mounting and dismounting a mounting bracket secured to a signal testing unit to and from a channel plate that is secured to a vehicle surface, the channel plate defining a plurality of channels and the mounting bracket comprising a housing and one or more clips, each clip defining a first U-shaped end and a second U-shaped end, the second U-shaped end having an L-shaped finger that is pivotally mounted within the clip, the method comprising the steps of:

• positioning the first U-shaped end of the clip to straddle an edge of one of the plurality of channels;
• pushing the second U-shaped end toward the channel plate such that a first arm of the finger is moved away from the channel plate and a second arm is pivoted in an outward direction from the clip, wherein the first and second arms straddle an edge of the channel and the second arm is adjacent a back side of the channel plate and the first arm is adjacent a front side of the channel plate;
• pushing the first arm of the finger towards the channel plate and pulling the bracket away from the channel plate such that the second arm of the finger clears the edge of the channel and moves adjacent the front of the channel plate;
• and
• pulling the first U-shaped end of the clip away from the channel plate.
