radio engineering; antenna engineering; mobile transceiver radio sets (radio centers). SUBSTANCE: antenna sheet (long wire) is placed above ground on insulating supports. One end of wire (sheet) functions as first power point and its other end is connected to terminal loading resistor ((R(N)l),). Antenna sheet (wire) is split into sections having lengths l1, l2...lN,. Filter cells are inserted in split points of antenna sheet each of them being also placed in shielding casing just like input filter cell F1, F2...FN-1 and loading resistor Rl (N) (loading filter cell FN). Filter cells have shielding casings arranged in magnetically isolated sections of (compartments) of shielding casing and interconnected through their low- and high-frequency filter inputs and these inputs function as filter cell input connected to finish of 1(i)-th (i = 1, 2 ...N - 1) section of antenna sheet;. Low-frequency filter output functions as filter cell output and is connected to start of l (i + 1) section of antenna sheet; high-frequency filter output is connected through series load resistor Rl (i) to point of connection of shielding casing just like common (ground) leads of low- and high-frequency filters. All shielding casings of filter cells Fi (i - 0, 1, 2 ... N) are connected at points of connection to ground insulated counterweights which are, essentially, two groups of conductors arranged perpendicular to antenna sheet. EFFECT: enhanced efficiency of antenna and, hence, reliability of communications. 3 dwg
