So speaking of the out of the box HI VHF yagi antennas. Are they generally designed for the middle of the spectrum? I mean how does the company come up with an antenna like the 30-2476 that performs well across the VHF High Spectrum?

Well, that is a question that is beyond my abilities to answer. My VHF antenna experience has been with ham radio antennas where the entire band is only 4 to 5 MHz wide. Narrowband Yagis are widely used because of their high gain and narrow bandwidth. Great if you only need to receive one TV channel, not so much if you want to receive the entire VHF-Hi band.
I would speculate that building an antenna to cover a band 42 MHz wide is much more complicated.
Have you ever taken a look at this web page that has a lot of info about a number of different antenna types?
