21. This then forms a 4 : 1 balun , which works correctly at only a narrow band of frequencies. 22. This balun design is impractical for low frequencies because of the long length of pipe that will be needed. 23. He has performed " Balun ", a popular Istrian dance by Bruno Krajcar with his sister. 24. With a balun , sheath currents can be avoided when a balanced line is connected to an unbalanced line. 25. Guanella is best known for the " Guanella Balun ", a high-frequency impedance adapter. 26. The administrator of the Hillside Health Board, Angelo Bonano, says Balun deserves " a medal ." 27. At most, Balun faced a small fine for killing the rat while it was trapped in a squirrel cage. 28. This balun design is not good for low frequencies because of the long length of pipe that will be needed. 29. One easy way to make a balun is to use a length of coaxial cable equal to half a wavelength. 30. Balun had made the mistake of calling the agency to come and get the rat after he killed it in July.
