Arrow antennas

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. 73 Ray W2RS

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.
