We have systematically studied the transmission of electrical signals alongseveral 2-strip Resistive Plate Chambers (RPCs) in the frequency range$f=0.1-3.5$GHz. Such a range was chosen to fully cover the bandwidth associatedto the very short rise-times of signals originated in RPCs used for sub-100pstiming applications. This work conveys experimental evidence of the dominantrole of modal dispersion in counters built at the 1 meter scale, a fact thatresults in large cross-talk levels and strong signal shaping. It is shown thatmodal dispersion appears in RPCs due to the intrinsic unbalance between thecapacitive and the inductive coupling $C_m/C_o \neq L_m/L_o$. A practical wayto restore this symmetry has been introduced (hereafter `electrostaticcompensation'), allowing for a cross-talk suppression factor of around $\times12$ and a rise-time reduction by 200ps. Under conditions of compensation thesignal transmission is only limited by dielectric losses, yielding alength-dependent cutoff frequency of around 1GHz per 2 meter for typical floatglass -based RPCs ($\tan \delta|_{glass} = 0.025\pm0.005$).  It is further shown that  `electrostatic compensation' can be achieved for an arbitrary number ofstrips as long as the nature of the coupling is `short-range', that is analmost exact assumption for typical strip-line RPCs. Evidence for deviationsfrom the dominant TEM propagation mode has been observed, although they seem tohave negligible influence in practical signal observables. This work extendsthe bandwidth of previous studies by a factor of almost $\times 20$.
