Halogen Light on TV aerial pole?

[dylanlennon]

Someone I know has asked me to fit a light on top of their roof & to fix it on toa pole that has his & his two neighbours TV aerials on it. I'm not to keen on the idea, is there any reason why this shouldn't be fitted on this pole, regulations wise?

1) This is in the wrong forum.

2) Why?

Why on earth do they want this? Surely up there will bee too high up, be flooding light all over the place (further than just their property) and then the council will likely be knocking...

Basically they have a hill in their back garden, they take the dog out there for the toilet so light would only be on for a couple of minutes. They want the light pointing up towards the hill which is higher than the house. I'm not overly keen on the idea as something tells me a 230v light shouldn't be on the same pole as a load of aerials! I think it would be better on it's own away from this.

My problem would be lighting strikes if the pole is earthed with the lamp then it would be a prime target for lighting strikes. With the 150W limit without planning consent it would need to be a discharge type which would need an earth.

If the light earths the pole it can lead to problems such as interference.

If they want the light on a pole, fit another pole just for the light.

Fixing it the the existing pole is not acceptable, as if there was a short or other internal fault in the light, some of the fault current would travel via the aerial wires.

There is already a possible problem in that the pole has aerials for more than one property fixed to it.

The pole should be earthed for lightning protection so fault current should not flow via the aerial cables. Even so it should be on a separate pole which should also be earthed.

How many aerial masts on domestic property's do you think are earthed?!

Very few. But that does not alter the fact that all of them should be.

Isn't the purpose of earthed lightning rods to 'attract' the lightning?
I.e. prevent it striking tall buildings.

So, just earth the neighbours' aerials.

The answer is not clear. Some say a pointed tip to the earthed lightning conductor creates an electric wind ( stream of electrons ) which discharges the local static charge thus reducing the risk of a full strike. Others say the stream helps create a path for the strike.

Fitting a mains powered lamp on an un-earthed aerial mast should be avoided. The aerial cables descending from the mast could then be considered as a potential source of extraneous potential and thus require bonding where they enter the building. ( a faulty lamp making the mast live is more likely than a plastic gas supply pipe becoming conductive. )
