Antenna arrays of series "I" (letter "I" - from "integrated"), namely, D2 UHF I and D4 UHF I consist of two and four dipoles D1 UHF, correspondingly, fixed on a mast and connected by all-soldered cable integrators without connectors. These antennas possess all the advantages of antennas of "D" series: broad operating bandwidth, practically circular radiation pattern, low sensitivity to the noise of industrial origin, the possibility to slightly change the radiation pattern of antenna array in H-plane, the steady polymeric coating. New antennas D2 UHF I and D4 UHF I are remarkable for their enhanced reliability due to all-soldered wiring.
For operating at the frequencies 450-540 MHz we have developed a model D4 UHF(H) I.
These antennas are provided with the detailed SWR graphs for various RP.
