Scaffolding tubes are usually 2" diameter. Buy a length from your
scaffolder, but make sure you get aluminium rather than steel.

I was about to say the same, also if you can manage it there are more
solid ways of fixing the pole to the brick work than a lashing kit.

CWB15 (pair) will hold a 2" pole for years without a problem and only
require one M10 rawlbolt each to fix to the brick.

Skymasts will also supply 2" thick walled aluminium tube cut to length.

The advantage of this is that 10 years down the line your pole and
fixings are just as good as the day you fitted them and not beginning to
rust or fall down! Just make sure you get a good mechanically sound
aerial and coax to go with it.
