MHC as an antenna

MHC binding a peptide in its peptide binding groove could broadcast the electromagnetic signal of that particular MHC+peptide configuration. If T-cell receptors can both hear this signal, and, also attach to MHC, perhaps by similar mechanism (or they could even evaluate the signal at close range without touching, but if they do touch then the electromagnetic attraction, and ability to resonate with signal, should have same cause. ) Carl Anton Bjerknes simple experiments in vibration and action at a distance from 1800s might apply there.

Would the force causing electromagnetic binding also cause stronger interaction with matching "lock in key" over distance than with non-matching ones, acting as a beacon?
