Topband: [Bulk] Top Loading wires

[Grant Saviers]

With an insulated tower, the cheapest EZNEC and other free NECs will 
yield good results.  Would you rather climb, cut, and trim a few times 
or spend $89 to get EZNEC?  Simple to learn.  And the demo version is 
free  eznec.com

I understand there is a point of diminishing returns on the top loading lengths.  The 4 wire angles will be around 45 degrees or as close as possible.    If I knew how to model ,or even had a modeling program, I would attempt this already relatively simple task to many.
