Why do you need a radar for an inland waterways boat anyway, I'm surprised
nobody else has asked this fundamental queston. Peter

Even if te radar gizmo weighs nothing, is the mast in a position where it
could be used as a handhold/leaning post?. If so, it'll need to be quite
robust.

Hi,

I am looking to make a short hinged mast for a radar aerial from
aluminium tube for an inland waterways vessel. The aerial weighs 4.6
kg and mounts on a plate 210mm x 210mm. Was thinking of using a 1 1/4
inch 16 gauge aluminium tube, with a flat 10mm plate welded across the
top. Total mast length around 2.5m, with approx 1.25m above the
pivot.
Grateful for any thoughts.
