Hi all,

Does anyone know what this object is?


1203934653 1232 FT0 Small


It seems to consist of a tall slender metal pole with a silver dome on top, that has a small nipple in the centre at the top. There are three of them in Newcastle (England) all within 1/4 mile of each other. Two are on top of University owned buildings, one of which is the tallest building for miles around. The third one (pictured here) is on the roof of a low lying theatre building right next to the previously mentioned tall building.

More detailed pics here:

I'd be interested to hear your thoughts...

-Richie,

My first thought is lightning detector and there are 3 of them to pinpoint the location of the strike (Lightning Detection and Ranging - LDAR).

It could be any number of other interesting things but that seems quite likely to me.

Some sort of secret radar/information gathering device? it could also be part of the early warning system.

We have one here, sited near the PEH, it apparently serves as advance warning in case Cap de la Hague blows its top.

I'd say thats a little far fetched.

With an antenna of that size, you're talking about an effective passive receiver for signals <10cm in wavelength, and an effective active detection system for wavelengths far shorter than that. Never mind the fact that the domes appear to be solid metal. Not especially useful for radars and the like.

There is an almost identical network here at Robins AFB. They are in fact lightning detectors. Nice things to have when you've got a 100 acre concrete slab surrounded by 90' stadium lights.

There are a number of other possibilities. Radiation detectors (highly unlikely in this case, but on a military base more plausible), Lightning protection, etc.

Here are some very familiar looking lightning sensors in use in Singapore. Link2
