The standard is 75 Ω (F-type or IEC connector). However, most half-wave dipoles are 73 Ω, and folded dipoles are 300 Ω.

DVB-T signals are broadcast in either horizontal or vertical polarization. A feature of many DVB-T antennas (especially "rabbit ears" or log-periodic outdoor antennas) is the ability to physically rotate the elements to match the polarization of the local transmitter. dvb-t anténa

While the antenna itself is technically just a piece of metal, a "DVB-T Antenna" is marketed specifically to connect to tuners that decode the DVB-T standard. If you are in Europe, Africa, or parts of Asia, DVB-T is the standard. If you are in North America, the standard is ATSC , and while the antennas look identical, the tuner inside your TV or box is different. The antenna itself works for both, but the label depends on the region.

Nemají zesilovač a spoléhají čistě na svou konstrukci. Jsou méně náchylné k přebuzení v místech se silným signálem a nevyžadují napájení. Příkladem je TechniSat Digiflex TT6. Klíčové technické parametry Home Indoor Digital TV Antenna Signal Antenna DVB-T2

Digital Video Broadcasting – Terrestrial (DVB-T) relies heavily on the receiving antenna's ability to handle impedance mismatch, multipath interference, and band-specific gain flatness (470–862 MHz). This paper examines the shift from traditional wideband log-periodic antennas to modern active and passive dipole arrays. Empirical data suggests that the common "set-top" passive antenna suffers from a negative Signal-to-Noise Ratio (SNR) below 45 dBuV/m, necessitating active Low-Noise Amplifiers (LNAs) with a Noise Figure (NF) < 1.5 dB.

: Best for urban areas within 20 km of a transmitter with a strong, unobstructed signal. DVB-T signals are broadcast in either horizontal or
