K9AY: diameter "solid wire" for the 25G tower (I used 5 inches). That sounds too small. Here's the formula I used to model my 160 vertical made of Rohn 45: http://lists.contesting.com/archives//html/

Bill and all, If I change from 5" to 8" the reactance moves the right way, but the resistance moves the opposite direction. The net result is that the model is a little closer to the measurement, but

said it originally came from IEEE Transactions on Broadcasting, but I don't have the exact chapter and verse. You might ask W1FV. After a little more searching: If you have access to the June 1998 is

Let me correct any confusion I caused... In my contribution to the discussion of tower equivalent cross-section, all my references should be RADIUS, not diameter. Thus, the reference uncovered by Bil
