I read a review of this antenna on Page 65 of the June 2017 issue of QST magazine and decided that I "needed" to have one. It is omnidirectional, horizontally-polarized, and intended for single-sideband (SSB), digital, or CW (Morse Code). Due to its light weight and compact size I intend to try it for 2-meter and 70-cm SSB during Summits on the Air (SOTA) activations.
It is made up of two dipoles in semi-circular configurations. The two U-bolts between my thumb and forefinger allow mounting to either of two sizes of antenna mast (one or the other is used at a time).
