I know that Mike, but how did they model it in the old days? They didn't have pc software back then. Somebody told me that they would do the math on it, the tower's height, impedance, etc and move the wire up or down until that go it at the right point.
An engineer from MTSU told me my ATU would be twenty feet from my tower, then start the point of moving the wire up and down until the right match was found. The tower climber would have to come on and off the tower each time it was move. I have no clue how he would have model it, but he does have the software to do it.
We didn't do it because it wasn't legal. If I had my way about it, I would have as the engineer from MTSU to do it.
