I think he also advocates separate ground rods for; /archives//html/Towertalk/2003-02/msg00244.html (7,701 bytes)
91. [TowerTalk] My favorite tower tip is... (score: 1): Author: n4zr@contesting.com (Pete Smith); Date: Wed Feb 12 15:26:21 2003; A loud amen. It's awfully easy, as well, to get diverted with thoughts of how the new antenna's going to work, or wondering whether you've fixed a problem. Keep your mind on the climb, and be safe ou; /archives//html/Towertalk/2003-02/msg00296.html (8,271 bytes)
