Page 45: Chapter 10 Maintenance
Maintenance Maintenance WARNING Whenever a rigger is on the tower in the area of the antenna, shut off the signal and lock it off so that it cannot be turned on accidentally. RF emissions at close range are hazardous. We recommend that you keep a log of VSWR readings and any other perfor- mance notes and maintenance history for your antenna. -
