This unit in natural finish anodised aluminium is a telescopic mast suitable for T.V. and other antennas. It will extend to 1.5 metres in 3 sections. The top section is 27mm dia., which is compatible with almost all T.V. antenna mounting hardware. The bottom section is 35mm dia., which would easily be accommodated by U-bolt or other clamping hardware (not supplied).
The top section has a sturdy cap and features a slot, which enables you to neatly thread the coax lead down through the mast.
