Scott, you are introducing sharp corners to your new antenna so NEC
will stray from accuracy.

Is NEC4 better in this regard?

Here is the NEC2 reported performance of my current design. Its a 24
foot boom, with 5 bands. 4 elements on 15-10 and 3 elements on 20-17.
Optimization is for F/R around mid-band and bandwidth (under 2.5:1 at
edges).

Click each band.html file to see the graphs on each band. The non-
active driven elements are shorted.

Here is the stock Cubex 4 element quad, which is 4 elements on all
bands (on a 24' boom).
