I'm sure many of you know how hard it is to drive long pieces of copper 
pipe into hard ground to make an RF ground, such as my yard which has a lot 
of clay in it.  I was wondering if it would be alright to fill a 5' piece 
of .5" or .75" copper pipe with quick cement to make it sturdy enough to 
pound into the ground.  If not what other method could I use to get the 
pipe into the ground?
