Guy wires are the obvious 'light weight' scheme whatever one uses for the b=
ase. I started off thinking in terms of the 4" square post holder that gets=
 hammered into the ground, as mentioned by someone previously, then guyed b=
y wires off to similar items also hammered into the ground. However to keep=
 the unit cost down it may be better to have the guy wires go to tent pegs,=
 with the wires being the fine nylon or similar rope used for guy ropes on =
tents, with the little plastic sliders to adjust the tension. If that is no=
t 'man enough' then use some rebar (possibly reclaimed from demolished conc=
rete structures - it would then probably come with the end already bent in =
a U) with some steel wire for the guys, and tensioners like used on the sta=
inless steel stays on yacht masts. Such tensioners are available in cheaper=
 versions as used on support wires that go across building spans to carry e=
lectrical connections across warehouse spaces etc.

All these items 'should' be easily removed from the ground with a car jack =
sitting on a suitable plank to spread the downwards force on the relatively=
 soft ground. The post holder may need a bolt through the post for the jack=
 to lever on, but it could be the end of a bolt holding the post in the hol=
der.

Any car jack should be potentially useable, it doesn't need to be hydraulic=
, although that may give the most ergonomic method.

Well, of course if using a guy rope system of some sort, the bottom of the =
pole does not need to go deep into the ground, just enough to stop the base=
 of the pole going sideways against the moment of the guy anchor point on t=
he pole. This side force at the bottom of the pole will be considerably les=
s than for an unguyed pole.
