[amsat-bb] Vertically mounted beam question

What sort of radiation pattern (mainly elevation lobes) would a dualband beam, like the Cushcraft A270-6S or Elk Antenna, have when mounted for vertical polarization? Does it have useful elevation lobes for most LEO satellite work? I used to have a Cushcraft A270-10S mounted horizontally and whichever band was on the top of the boom had some very high lobes with nothing on the lower parts of the passes.
