I don't know if RS still sells this stuff.  It was called a ground  mount, 
or drive-in base mount.   If you can't find wall brackets there, Channel 
Master still makes them.   You can get some part numbers from the below link 
and maybe find them somewhere local.   True-Value hardware stores may still 
carry Channel Master stuff.
If you can't find the ground mount, Homo Depot has fence posts in the garden 
dept.    Either 4, 5, or 6 ft. long.  They have a flange welded  at the 
bottom end  that gets driven into the ground.   Pick the largest one that 
will fit inside your mast and cut to  needed length
