PCT No. PCT/FI96/00580 Sec. 371 Date Jul. 1, 1997 Sec. 102(e) Date Jul. 1, 1997 PCT Filed Oct. 30, 1996 PCT Pub. No. WO97/16937 PCT Pub. Date May 9, 1997The invention relates to an interference-protected method and arrangement for supplying power, wherein the power supply between main devices and a masthead preamplifier of a base station in a cellular radio system takes place through an antenna line, and overvoltage formed on the antenna line is conducted to the ground by means of an overvoltage protector adapted for radio frequencies. The use of separate cables and separate overvoltage protector for the supply cable is thus avoided. |
