I'm not sure. I'm no engineer, post that on the Ham list and you'll get 15 opinions with graphs and studies from 1968 proving that you don't need to mount it on the roof at all. For me, it just looks more stable since it comes out then returns to the same plane, possibly putting less stress on the mount. Dunno. I don't see where it would be any less effective either way.
