This minimises working voltages within the balun and ATU (reducing risk of flashovers), without driving high losses in the ATU are very low impedances. If you think about your own requirements, and finding a solution that fits, you will do better than Googling up HamUniverse articles and the like. Owen When I calculate the feedline length am I correct in assuming that I need to take in to account the velocity factor of the 460 ohm ladder line? Michael Rawls KS4HY |
