The DB4 from Antennas Direct has become one of the most popular models of HDTV digital antennas because it is simply one of the bests mid-range HDTV antennas on the market. With an approximate 13.7dB of gain, it is one of the strongest multidirectional antennas available and performs consistently across the entire UHF spectrum. It even works well in areas where HD transmitters are sending in signals from multiple directions. The bow tie design of the DB4 uses triangular elements instead of rods to greatly increase the bandwidth allowing it to cover the entire UHF band.
