As discussed at the LUG, it includes a calculator for checking that your
tube is the optimal length & diameter as well as an explanation of the
maths, test results (1km line-of-sight with a 10m target zone) and
important notes on quality of construction.

"Home Bargains" had perfectly dimensioned stainless steel toilet brush
holders (with brush!) for about £3 a little while back.
