What about a vertical omni connected via RG-174 coax to a short beam
pointed straight down?

I've seen commercial applications using two beams back-to-back in
order to connect two buildings together or multiple floors together
for 900 MHz spread-spectrum data radios.  The data radios themselves
had no physical connection to the antennas.  There were passive
repeaters.  Worked great.
