WebInstructions. This tool calculates the matching network necessary to terminate a line of the specified characteristic impedence (Z o) in a specific complex load impedence (R L + jX L) at a specified frequency. It supports both balanced and unbalanced lines. The tool provides two networks that will have the desired impedence at that frequency ... WebThe Balun on the end matches the 450 Ohm Open Wire Line into a 50 Ohm Coax Cable. The antenna as fed, matches reasonably well into a 50 Ohm Coax Cable Feedline. A …
WebAn open wire high impedance feed line is highly recommended. That's why I chose to feed my OCFD with 450 ohm ladder line: its characteristic impedance will likely be closer to the higher impedances of an off-centre fed dipole than coaxial feed line;
