It's also important to remember that those long telephone transmission lines were also twisted pairs, to reject magnetic coupling from the power lines that ran on the same poles. Because their concern was power, and the low order harmonics of power, the twist accomplished by crossing over every pole or two. To understand this, do a quick calculation of the wavelength at 120 Hz. :) 73, Jim K9YC _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec |
