ABSTRACT
If the loads number is large enough and they are located at small electrical distances from each other, one can consider that the loads are included along the entire length of the antenna. In order that the concentrated loads may efficiently influence the current distribution, the distance between them must be small in comparison with the wavelength. Calculation and experiment confirm that characteristics of antennas with loads are much better than their characteristics without loads. The upper limit of a frequency ratio for antennas with loads is determined by a deviation of the main lobe of a vertical direction pattern from a horizontal direction. The frequency range was split into short intervals and the capacitances of loads used in each interval were equal to capacitances calculated for the middle of the interval. Together with the method of impedance long line it was proposed another approximate method for calculating magnitudes of the loads, which provide the given current distribution.
