[Antennas] Only dumb question is the one not asked

Hi Gang,
I hear so many times (and I have done it myself) make a choke buy winding 6-8 
turns of coax at the feed point to keep RF from coming down the feed line.
OK,
RF is on the line.
You make 6-8 turns and there is no more RF coming down the line.
How does this work?
What keeps the RF from just traveling around the turns and keep on going?
Also what if I exposed a bit of the braid right after the last turn and 
grounded the coax there.
I know this list has some smart EE's and antenna experts.
My other question is a brain basher so i'll save that and post it on Monday.
Happy Easter to all.
