Concept sounds like a coaxial dipole, much like the old Shakespeare "Big Stick", except utilizing wire for the non-coax portion and running it horizontal/inverted V or whatever can be fashioned for a lower band.  Bill Orr, ref. Simple Low-Cost Wire Antennas], in chapter 4 describes something similiar and used as a vertical.  On p. 114 of the same publication a somewhat similiar design utilizes a ferrite core choke wound with several turns of coax to decouple the feedline, but actually using a 1/4 wave of feedline as the 'other-half' of the dipole configuration (a Cobra Antenna).  If you cannot center feed then a ham does what he has to do, improvise.
