Current baluns are superior to voltage baluns in almost every scenario

Current baluns and voltage baluns have similar performance to symmetrical antennas like horizontal dipoles and yagis. However, due to capacitive effects in the vicinity of the antenna, a dipole may not always be “balanced”. For that and other reasons, it’s preferred to use a current balun rather than voltage one since it works even when the antenna is not perfectly balanced. (Also, current baluns are easier to test.)
