I have two questions:

        - to transmit omni-directional horizontally-polarized,
                are they using some kind of 'halo' design?

        - What kind of antenna would radiate a circularly-polarized
                yet omnidirectional pattern?  I've never seen
                any circular designs other than twists and dishes.
