Thanks for the compliment, 300ohm. Last night I was able to get the second iteration modelled, though I had to up the number of symbols that 4nec will evaluate. I could have spent a little more time simplifying my model to do that, but I just upped the max symbols to 128 instead. Anyway, close to the same results, but it looks prettier and is shorter (but not less wide)

Two lengths of 1468 mm long 12 gauge wire form the elements and the middle segment is 433mm long (which will get split in the middle for a 4:1 balun) Hopefully I can find time to build this soon.
