Shunt feed antenna
Did you know?
WebShunt-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. WebThis borrowed capacitance, and the shunt matching coil's inductance, form a highpass, LC network which transforms the antenna's low impedance (typically 25 ohms or so) to that of the 50 ohm feed line. Installed and adjusted properly, shunt matching will provide a decent match (<1.6:1) over several octaves.
