The Iskra DTM-40-7 CF is a Yagi-type outdoor UHF antenna mechanically tuned to channels 21–48. It is designed specifically for the reception of digital terrestrial signals in DVB-T and HDTV formats, providing gain of 11.5–16 dB across the UHF band.

The antenna features a metal reflector for improved front-to-back rejection and is fitted with an F connector, allowing direct connection to standard coaxial cabling without adapters. At 118 cm in length with 40 elements, it combines high directional gain with the structural rigidity required for permanent outdoor installation.
