Here is a cheap, but neat, flag pole....
This flag stands about 40" tall. It sets on a stake allowing it to rotate with the wind.
It is made of PVC.
The above is 1/2" but you can use 3/4" as well for a bigger, taller flag
You will need---
A 5' piece of 1/2" PVC, 2 end caps, a Tee and a 45° elbow and of course a flag.
Cut the 5' piece into 2- 2' and 2- 6" pieces
Assemble as pictured.
Use a 10' piece of 3/4" to make a taller version which can fly a 3' X 5' flag
Cut the 10' into 2- 4' and 2- 1' pieces.
Use 2- 3/4" caps, a Tee and a 45° elbow
NO CEMENT IS USED on any fitting.
I can and will help anyone to make these up at the rally.
Just bring the materials and it's done.
I do have a few large and small flags with me.
