The DB4 has become our most popular model because it is simply the best Mid Range HDTV antenna on the market. With an approximate 13.7 dB gain it is one of the strongest multi-directional antennas available and performs consistently across the entire UHF spectrum. It even works well in areas where HD transmitters are in 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. Additionally the mesh reflector of the bowtie is more efficient than a rod reflector is lower in weight and provides less wind resistance for greater performance and durability. If you are looking for an antenna that is practically guaranteed to perform the DB4 is one of your safest choices. It will pull in all UHF frequencies and most higher level VHF frequencies with a range of about 55 miles.
