THE BASIC PRINCIPLES OF SUBWOOFER

This inexpensive approach tends to end in towers that may be spaced an eighth of the mile or much less apart for circuits about the lower end of the voltage scale, sixty-200 kV, and as much as 1 / 4 mile aside for the upper voltage circuits similar to the five hundred kV lines. Supporting 1 / 4 mile of steel wire isn’t straightforward possibly, I
