Good Morning All: For the EZ-Nec users here on Topband, when modeling a grounded shunt fed tower with guy wires insulated at the tower, where do you place the source? The feed is #8 insulated wire spaced about 18" from the tower leg. 73, Mike, W5UC "age & treachery will overcome youth & skill" http://www.suddenlink.net/pages/w5uc/
