Hello the list,

          Has anyone considered a 'Slinky' Beverage for 500kHz? For those not familiar a 'Slinky' is a toy spring approx 8cm in diameter. Stretch out the 'Slinky'  (or several 'Slinkys in series) and you have an inductively loaded Beverage, a way of shortening the antenna mechanically.
