Hi. I'd be curious in hearing how things work out. I typically run a 3 element yagi on 50 MHz for my Portable / Roving efforts. Setup time including a dedicated 20 to 28 foot mast and base is approx 20 to 30 minutes (depending on my energy level, light levels, weather conditions, mast height etc.)
I'm always interested in alternatives, my other 50 MHz roving antenna is a 1/4 wave whip which is not a great performer most of the time.

After all when you squash quad elements all the way down they become folded dipoles. The 2 element quad can also have really good front-to-back ratio, while the F/B for a 2 element Yagi (with straight elements, not a Moxon) is quite poor. So there is probably a point in the squashing process where the F/B really degrades. But the numbers on the eantennas.es website certainly look to be about what I'd expect.
