Air Termination
Air rods & terminals to IEC 62561 — the strike-receiving end of the lightning protection system.
Solid copper air rods from 500mm to 2000mm, multiple points, bases, brackets, couplings and strike pads — plus free standing and wall mount masts that raise terminals up to 10m.
The Air Termination Range
Air termination is the part of the lightning protection system that intercepts the strike — rods and terminals mounted at the highest points of a structure, connected through the down-conductor network to the earth termination.
Unitech air rods are manufactured to IEC 62561-2 in solid copper, with tinned copper and aluminium versions throughout the range — diameters from 14mm to 25mm and lengths from 500mm to 2000mm, plus multiple-point finials that screw onto the rod.
Every rod is matched by its bases and fittings: tape and cable bases to IEC 62561-1, ridge bases, brackets, rod-to-tape and cable couplings, and strike pads for flat roofs and exposed conductor runs.
- Air rods to IEC 62561-2 — solid copper, tinned copper and aluminium, 14mm–25mm diameter, 500mm–2000mm long.
- Air rod bases to IEC 62561-1 — for copper tape use and for cable use, in matching materials.
- Matched materials — copper, tinned copper and aluminium across rods, bases and fittings, to suit the conductor system.
- Masts to 10m — free standing and wall mount masts in stainless steel 316 or galvanised steel, suitable for air rods, strike pads and ESE terminals with an adapter.
- Custom sizes on request — other mast sizes and dimensions can be supplied to approved drawings.
