The present invention discloses a class of independent or linked facing tuning elements to be used in loadpull high gamma slide-screw tuner consisting of a radio-frequency transmission media comprising impedance tuning elements such as probes, corrugated probes, multi-section probes or single stubdouble stub harmonic resonators. A cross bar may be attached to the main vertical beam element of the forklift. A wireless telephone communication can then be established between that telephone apparatus and the slave communication device without relaying through the master communication device, and without requiring particular processing, such as authentication on a host station side.
