Television & Radio Hardware - Brackets and Clamps

Standard brackets are the most commonly used, with a range of sizes depending on the stand-off required and the size of the pole to be supported. They can support relatively high loads, with multiple standard brackets able to be used if necessary.

T&K brackets consist to two bracket portions, and are significantly stronger than standard brackets. They are used to support large poles with larger loading, or in situations where a bigger stand-off is required and a crankshaft pole is not suitable. If the wind loading is expected to be even more significant, two K brackets could be used to provide extra strength.

If no additional stand-off is required (such as on a flat roof building or wall), low profile brackets can be bought which reduce the distance the pole is from the wall to around six centimetres.

Tile mounts are suitable for light loads on installations where a pole can not be used. They are designed sit on the sloped roof and hook in under the roof tiles though there is no requirement to drill. A stub pole is used to mount the aerial into, however it must not be extended.

A tilting bracket is also available which allows the base of the pole to be mounted to a surface that isn’t flat. It is only suited to low load applications.

Chimney installations are relatively common as they usually provide additional height for the aerial. They should be fitted using a lashing kit. The lashing kit provides a mitre bracket, steel wire, and plates on which the wire rests when wrapped around the chimney. Its use is important to spread the load. Alternatively, a heavy duty lashing kit can be found for bigger loads which come with two brackets and two lots of steel wire. Brackets should not be used on a chimney as the stacks are not strong enough to support the load of an aerial fitted in this way.


A common sight on older aerial installs is the use of cheap brackets. Particularly near the sea where the salt air quickly starts the corrosion process, brackets and mounts begin to rust and produce staining on the wall they are mounted on. It is better for the long-term installation and general appearance to purchase hot dip galvanised products which can spend years if not decades outdoors without rusting.

Also be aware that smoke (from chimneys usually) can exacerbate rusting, so aerials ideally should be placed away from chimney stacks which are used to burn coal or other materials.
