<p class="Abstract"><span lang="EN-US">Digital dividend and UHF frequency bands change over from broadcast television to mobile communication are being coordinated all over the European countries. The necessity of higher spectrum efficiency is a mandatory requirement for designing terrestrial digital video broadcasting servicing. To this context, designing higher servicing area in single frequency network configuration is one of goals of spectrum efficiency for TV broadcasting. In this work are analyzed four different DVB-T2 modulator configurations for merging two existing SFN’s within use two frequency channels to a new one extended SFN comprising both existing areas and a single frequency channel. The goal in the analyzed case is to reduce at minimum physical network change as transmitting antenna sites, antenna radiation pattern and transmitter radiated power for both allotments without also worsening the total bit rate. The proposed analysis is performed not only in received signal strength on the new SFN area, but signal quality and self-interfering definitions are described and simulated for the real test case in Albania allotments. The proposed solutions show the applicability of the designing method for extending the SFN area also beyond the theoretical permitted by Guard Interval choice.</span></p>
