An antenna distribution unit distributes an input RF signal comprised of multiple discrete antenna feeds to a plurality of electronic devices in communication therewith. The antenna distribution unit engages in three-way signal splitting across a pair of successive splitting stages in order to produce an even multiplicity of high-quality signals across nine output ports. By limiting signal splitting to two splitting stages and carefully selecting components to maintain series and parallel impedance, a high-fidelity output signal is produced having an essentially flat spectrum over the target frequency band. In particular, the antenna distribution unit is optimized for use in the distribution of signals within the TV VHF low band of 50 MHz to 88 MHz, the TV VHF high band of 175 MHz to 213 MHz, the TV UHF band of 470 MHz to 610 MHz, and the 900 band of 900 MHz to 1000 MHz.
