Screw in is the only easily removable thing and also works in stony=20
ground. Will give best resistance to being pulled out.

I have a pair of clothes drier line  screw in bases. They have a slide=20
in bar to screw it in/out. No hammering or extraction problems.

one for a pole.
or
three for three poles in tripod
or four for 1 x central pole and 3 for  steel wire guys

About 10 Euro each.

About 35cm to 40cm long, like giant hollow wood screw. Has plastic=20
concentric "spacers" that fit inside top for different diameter poles.

I bought them for Temporary Radio Mast bases. Works well with 6m mast=20
and no guys. I was going to try two 10m poles (clamp together=20
concentric/telescopic) with two guys on each pole and  20m to 80m caged=20
dipole between them.
