I agree.  I've already moved away from omnis for portable work.

That's exactly what I plan to operate!  I already have a stand I can use for 2m
and 70cm

Indeed!  This should be fun, and the antennas will again be suitable for
portable work, especially on 1.2 and 2.4!  10 GHz might get tricky with narrow
beamwidths though... :-)
