All the elements are 2' 4-13/16'' for real channel 10, the only channel I have trouble catching.
How do I wire it? The only wiring I have ever seen was for a UHF antenna that had 4 bowties. The balun tied in at the middle, and the wiring started from the top bowtie, crossed over to get to the 2nd bowtie, then went straight down to the 3rd bowtie, then crossed over to get to the last bowtie. Assuming that was correct for UHF, would that be the same for four VHF elements?
You have departed considerably from the example I posted. The example is two stacked halfwave folded dipoles.



A bowtie antenna uses fullwave dipoles:



If you want to use the bowtie design, it would need to be TWICE as wide.

The bowtie antenna is derived from the collinear array, The bowties instead of the straight elements gives greater bandwidth.
