    Antenna arrays of series "I" (letter "I" - from "integrated"), namely, D2 VHF I and D4 VHF I consist of two and four dipoles D1 VHF, correspondingly, fixed on a mast and connected by all-soldered cable integrators without connectors. In addition to all the advantages of antennas of "D" series (broad bandwidth, low sensitivity to the noise of industrial origin, the possibility to slightly change the radiation pattern of the antenna array, the steady polymeric coating) an enhanced reliability of the antenna is provided due to all-soldered wiring.
