I saw this device along a trail while hiking in hills in the suburbs of Taipei. It sits on short legs only about 1.5 meters tall.
It has two attachments which appear to be thick cables but I couldn't tell for sure, the area is overgrown and behind a bit of a fence. These are the best zoomed photos I could get.
The exposed red cylindrical section in the middle appears to be made from some kind of dielectric insulator or maybe fiberglass, and I estimate it to be about 38cm (15 inches) long and about 10 cm (4 inches) in diameter.
If it were a base-loaded antenna I'd expect at least a little more radiator on top, and one coax instead of two cables. I don't think it's a red light either, it doesn't appear to me to be even partially translucent.
I've cropped the best view of the label. I can make out ingelva parafulmini and Varese Italy. The The part number is very difficult to read, and I've obscured the four digit serial number for a bit to anonymize the end-user. I don't know what this is nor whose it is, but it sets only about 2 meters off of a popular hiking trail and so it's at least not "top secret".
