I use a horizontal omnidirectional antenna for 2M in the truck while
working SSB. Most home-based 2M SSB stations run horizontal
polarization (at least here in the USA). I use it to help avoid the 20
dB or so loss that occurs from crossed polarization.

As for short range mobile and portable communications, propagation
relies so much on 'bouncing off things' that it probably doesn't matter.
Circular is probably best, but vertical physically easier. I can't
imagine why anyone would want to use horizontal.

Cheers,
