"Speculation is not required, if made with 3/4" or larger materials they will surely cover way
more than 6 MHz flatly, but they are usually mounted vertically, if mounted horizontally they
produce a figure 8 pattern. They are simply an end fed dipole. (often homemade with copper tubing)
A permanent emergency antenna would normally be crossed dipoles fed 90 degrees out of phase.
(for one bay)
