Absolutely ... a much easier design is a non-metallic conduit box
with cover, a couple of fittings, a 10' piece of 1/2" or 3/4" *aluminum*
conduit, a dowel that will fit into the conduit snugly
and a couple U-bolts to fit whatever mast you're using.
If the mast is bigger than 1.25" you may want to dispense with the
conduit box and use half or a quarter of a cheap HDPE cutting board
with a pair of U-bolts to fit the outside of the conduit. However,
everything for the conduit box version is typically available at
your local Home Depot or Lowes.
The same general construction could be used for 10 and 12 meters
except I would stick to 3/4" conduit and it will take two pieces.
