Well the neutral line isn't really required on the high voltage feedlines. Our power line used to come directly from the ridge across the road, an 800' span 200' above the road.. Several times we fou

I think one reason for the variations is that standards (calculations) have changed over time (thank the lawyers?) In 1971, I put up a Heights 72' aluminum tower. It required a 4'x4'x4' concrete base

96 consecutive hours (so far this week) basically unattended. It would appear that the operator intends to work DXCC on 20m without even being in the room with the radio. Be careful of what you ask
