rendered unusable for communication conductors due to the CMRS antenna is 1 foot (i.e., the pole space between 5 and 6 feet below the power lines can no longer be used for communication conductors due solely to the installation of the CMRS antenna). Example 2: Pole Space Immediately Below Power Lines Operating at 7,500 50,000 Volts. The minimum safety clearance between power lines – operating at 7,500 50,000 volts and a communication conductor is 6 feet. The minimum safety clearance between power lines operating at 7,500 50,000 volts and an antenna installed below the power lines is 6 feet. Thus, for power lines operating at 7,500 50,00 volts, it would not be possible to install a – communication conductor in the first 6 feet below the power lines, with or without the CMRS antenna. In this example, for the pole between the power lines and the CMRS antenna installed 6 feet below the power lines, there is no pole space that is rendered unusable for communication conductors due to the CMRS antenna. Example 3: Pole Space Immediately Above Power Lines Operating at 750 7,500 Volts, Attached 6 Feet Below the Pole Top. Power lines operating at – 750 7,500 volts must maintain a minimum safety clearance of 4 feet from other power lines attached to the same pole operating at 0 75,000 volts. So, if power lines operating at 750 7,500 volts are attached 6 feet below the top of the pole, – there would enough pole space to allow another set of power lines operating at 0 75,000 volts to be attached at the top 2 feet of the pole. Power lines operating at 750 7,500 volts must maintain a minimum vertical safety clearance of 6 feet from an antenna. Therefore, an antenna
