I did say that this was transportable, didn't I?
If you don't have a car with at 1.2m x 1.2m x 2.4m storage compartment, then try the following:
Remove upright from base.
Remove 4x 600mm pipes from base strut.
Rearrange to form a bundle of pipes ~2.4m long and <100mm in circumference.
If you want to get REALLY clever-pants, then cut the upright in half, and add a pipe-collar or use a piece of pipe with integrated joiner so that you can fold the thing down to only ~1.2m long, just like in the photo.
