The sand packed base also allows one to make small plumbing adjustments in
case the mounting arrangement is not exactly vertical.
I built one of these masts back in the early 70's when very inexpensive used
oil field tubing was readily available. The mast served well for a few years
supporting a three band Quad and Mosley CL33. Later it was cut up to make
guy posts for a larger tower.
Steel suppliers will be able to furnish modern replacements for the original
well casing design. One could also use analyze wind survival by means of the
currently available computer mast stress programs. The steel suppliers can
give you the needed yield strength specs for their products.
