Doug,
The problem, as I see it, is that 2m and 70cm are harmonically related. If the two Yagis were in the same plane, there would be more interaction between them. Placing them 90 degrees apart minimizes such interaction.

I am program coordinator for the Coastal Plains ARC for 2019. We meet in
Tifton Georgia on the second Saturday of each month. I was wondering if
there was someone close by who would be willing to do a presentation on any
of the Amateur Satellites. If you are interested, please email me directly.

Images of Ultima Thule from the Long Range Reconnaissance Imager on New
Horizons are being posted at:
http://pluto.jhuapl.edu/soc/UltimaThule-Encounter
They don't look like much today, but we expect to see much better images in
less than 24 hours.
The entire mission results are at http://www.pluto.jhuapl.edu and the PBS
program NOVA will do a special show about the Ultima Thule encounter on
Wednesday evening on your local Public Broadcasting station (in the USA at
least).
