It is an object to provide a tuning circuit which has large fractional frequency band width, for example frequency band of the return loss of less than \u221210 dB. The first jamb clip is positioned adjacent to a right side of the panel body and the second jamb clip is positioned adjacent to a left side of the panel body. The inner ferrule is disposed between an inner insulation jacket of shielded electric cable and an exposed end portion of a conductive layer surrounding the inner insulation jacket. A second connecting wire connects said second conductive layer to an output terminal of the power amplification device. The leveling linkage has adjustment features that allow for compensation of camera lens angulation caused by movement of the camera supported on a vehicle rolling over rough or uneven ground. The handheld device includes image capturing capability and an orientation sensor, which provides a signal representative of orientation relative to gravity to calculate an angle of rotation for the captured images suitable to compensate a difference between the orientation of the handheld device and the orientation relative to gravity.
