An impedance matching, harmonic electromagnetic tuner has an airline with multiple slots to reduce the overall length of the tuner. At least one RF probe is disposed within each slot so that it can be moved parallel to, towards and/or away from a center conductor. Each of the probes may be put in user selectable positions to create a user selectable impedance.
