It is a secret Illuminati communication device. 

Obviously nothing to do with 5G or it would be melted and charred.

It is a secret Illuminati communication device. 

 

It does look phallic, and we all know secret organizations love their phallic symbolism.

I'm gonna put money on some sort of wide-area RF transmitter? Public WiFy perhaps?

As my grandad would say, it is a wigwam for a gooses' bridle 😄

Oblivian: Yagi antenna.

As others have observed, it's a weather-protected Yagi antenna.

From what little we can see, it looks like there's quite a bit of 'stuff' on that pole, so it's almost certainly the lines company's SCADA system radio link. If it's in an urban area, probably UHF; if it's rural it might be VHF

The spark 'wireless' push is for routers with 3G/4G Cell units that use the cellular network and deliver you internet/VoIP - not wifi.

That, is a directional antenna made to send as much signal as possible in 1 direction to a device in the direction its pointing. Focusing it if you will.

Be it, wifi (not likely at that length) to give another device (like a camera or monitoring equipment) on the pole a connection to something further away. Or make a stable link to something like an out of line of site cell tower

I've seen them used for water/flood monitoring. With a sensor nearby and the pole just giving it the height advantage it needs.

https://www.gowifi.co.nz/directional/ant-252.html Can't tell from proportion if it is in this range or longer/UHF.

It isn't made to provide a connection to lots of other things. Just a good one to 1 thing.

Stand under it, face the direction its pointing. And use google earth or similar to draw a line for ~30Ks and you'll find what its pointing at. Likely a cell tower on the top of a hill quite a distance away, or just peaking over something blocking a direct path

ronw: [snip] I know that Spark have been pushing wifi to replace using Chorus fibre.

No they haven't. WiFi would be used to create a network within a building. The fixed wireless product uses a cellular connection as through it were a cellphone. It just talks to a normal cell tower.
