Abstract

Die Empfangs- und Sendeantenne besteht aus kolinear ange­ ordneten Dipolen 2, 3. Auf der Seite der End-Halbwellen­ dipole 2₁, 3n sind je ein Viertelwellendipol 6, 7 ange­ bracht. Die Dipole wechseln sich mit einer Phasenverschie­ bung mit kapazitivem und induktivem Charakter von 60 bis 120° el. ab. Die Herausführungen sind asymmetrisch vom freien Ende des einen End-Halbwellendipols 2 und vom benach­ barten Ende des benachbarten Viertelwellendipols 6 heraus­ geführt. The receiving and transmitting antenna consists of colinearly arranged dipoles 2, 3. On the side of the end half-wave dipoles 2₁, 3 n , a quarter-wave dipole 6, 7 are introduced. The dipoles alternate with a phase shift with capacitive and inductive character from 60 to 120 ° el. The leads are asymmetrical from the free end of one end half-wave dipole 2 and from the neighboring bare end of the adjacent quarter-wave dipole 6 out.
