Lightning precautions on rooftop antenna?

Are there any devices or precautions I should bear in mind if asking a professional installer to fit a roof mounted pole for a 4G antenna?

I am thinking of a 2-3m pole with a pair of yagi-type antennas, 1m coax cables terminated in Type-N connectors to an outdoor modem/router that then runs down the side of the house over Cat5 to my PoE switch.

The building is a bungalow with much taller trees nearby and one taller property within 50m

Almost impossible to protect against a direct strike. All you can do is make sure the installation is well and truly connected to an earthing point. A substancial earth rod and very thick cable.

Don't ever recall seeing lightning protection on tv aerial installs which are usually above roofline

We once had a direct hit on our TV arial - just blobs of aluminium alloy all over the garden and a bare pole on the chimney stack, coax cable burnt through in several places, and a dead computer that was on the other side of the wall where the coax ran down.

Surely a suitable lightning strike system offering very low resistance to earth is the way to, which means the lightning is more likely to hit that than your antenna

You can also end up with your house on fire, holes in the roof, plaster blown off the wall where the lightning strike used the house wiring as a path to earth, the list goes on.

You would need proper lightning protection, aka a thick piece of copper to the ground and proper grounding. This will be expensive. Even with all this a nearby strike can still take everything out with raised ground potentials. The lightning strike for a brief moment raises the ground potential near the strike many thousands of volts, which can raise the earth potential in the house and electricity from the strike starts flowing in the wrong direction...

Frankly in the UK the main solution is insurance as we don't get sufficient lightning to make it an issue unless you have a tall building.

+1 as seen on church spire's.

As the Vogons say "Resistance is useless".

I thought that was the Borg.

Hi,

The Borg was "Resistance is futile" not useless......Direct quote is "Your biological & technological distinctiveness will be added to our own. Resistance is futile."
