I used a Big Wheel antenna quite successfully mobile for some time...the design originated in VHF Comms magazine Edition 4, 1979. It comprised 3 wire loops each 22.2cm long in a clover leaf configuration soldered to a N type bulkhead connector, on end of each loop soldered to the centre spigot, the other 3 ends soldered to ground.

As its quite a compact antenna they can be stacked too.

One can also re-dimension a 2meter halo antenna for 23 cms too.

Both are for horizontal polarisation operation.
