[TowerTalk] CQ article error(?)

[Carl]

My 3 wire drop comes from the telephone pole in my back yard, across my yard, to a metal pole on my house.  Through this metal 
pole
the 3 wires enter my house to my inside fuse panel.  Should I ground this outside metal pole to an outside earth ground rod, and 
connect
 it to my tower grounds ?

Confused,
