Digital HDTV antenna specifications include Frequency Bands (VHF: 54-216 MHz, UHF: 470-608 MHz), Gain (dB, with higher meaning stronger signal capture), Impedance (75 Ohms for most home systems), and Standing Wave Ratio (SWR, with lower values like <=1.5 indicating better signal matching). Other factors include antenna Range (distance from transmitter), Polarization (horizontal or vertical signal), and antenna Type (indoor, outdoor, directional, omnidirectional) to match broadcast signals and your location's specific needs.
