The analysis of features of assessing the security of information processed in a computer from leakage due to ultra-wideband pointing to random antennas (RA) has been carried out. Improved formulas for calculating achievable values of the signal-to-noise ratio were developed, following from the optimal receiver model. For this purpose, a currently missing majorant model of the RA's effective length in the UWB frequency range was constructed, and the minorant models of the RA and receiver noise coefficients were refined.
