The best matching system for feeding a grounded Marconi element, unless we are very lucky or very careful in planning the installation, is a simple gamma capacitor and shunt feed conductor with the tap point adjusted to find 50 ohms resistive. WebAbstract: Shunt-feeding techniques are used to improve the impedance characteristics of the moderately superdirective normal-mode helical dipole. A novel broadbanding effect is observed, and a VSWR less than 1.65 with respect to 21 \Omega over a 3 percent bandwidth is obtained with no degradation of radiation pattern. malacca food blog 2021
