Yes, the "meander loading" approach works - you'll see something similar (implemented on a PCB) used for the integrated antennas in cellphones, Wifi routers etc.

Another option for the OP would be a short loaded vertical - again, the 'loading' can be done not by the traditional coil-and-capacity-hat method but by making up an insulating frame to support a large-pitched flat-helix of wire.

This method reduces the peaky 'really-narrow-bandwidth' issue that generally arises with very short inductively-loaded antennas.
