Thanks, Piotrek. That's quite a gap!

Tokyo is building a 256M tower right now if you're interested here's the thread: http://www.skyscrapercity.com/showthread.php?t=1218491

Actually Tokyo is building many buildings from 90-250 M right now. You can check them all here: http://www.skyscrapercity.com/forumdisplay.php?f=2663

The problem with skytree is it's kind of far from Tokyo's main districts.

Fags.

It looks so lonely there all by itself. I say, build some 200 meter towers around it and a supertall or two or three

I can't believe I just noticed there are really four cranes instead of 2.

Not all of them will be working at once I believe, some are for backup.

You're obviously not only not a telecom engineer, but have no knowledge of rf whatsoever. None of the transmitters on that tower are remotely "high power" and the decrease in signal strength from zero to 500 meters will be more than the decrease from 500 meters to 20 kilometers.
The rf you get from a cellphone next to your head will be a thousand times what you get from the tower at 500 meters, even if you were somehow high enough not to be under the very directional spotbeams they'll be using for most of these systems.

Good slammage Nomad, I hate when people say things like that they don't really have a clue about.

Thank's to Tommyzion pics now we are sure they removed the netting around the top mass damper!
I was thinking about that since fews days, but at that time we didn't had close-up pics to be sure.
Now I hope they will remove all of this crappy netting! (fingers crossed)
Anybody knows if ther's any such plan?

Don't worry, all the netting will be removed.

They even had those nets around the tower cranes, it's just protection (both for the tower and the workers) against the elements during the construction.

Not "high-power"??! You are hilarious as you are ignorant, lol. (there are 640 omni-directional antennas on that spear, each with a power of at least 10Watts. You do the math...)
Tell that to the people that got cancer and leukemia living in buildings that have on top GSM or Wi-Fi transmitters And those transmitters are just a fraction of what is installed on that monster...

They're not omni directional. In fact they're extremely directional since they're transitioning to centralized spot beam type systems instead of hundreds of little towers, and nobody on the planet calls 10 watts "high power".
In language a phony engineer can understand, that means you'll never see the signal from more than 1/2 dozen of those transmitters at any one spot.
And the cancer link only exists in the imaginations of people who flunked toll taker school and wear tin foil hats. Sort of like people who ignore the fact that a phone putting out 100mw 2 inches from your brain is ludicrously higher rf signal strength than a tower full of antennas a few hundred feet away.

Bro, you have absolutely no clue of what you're talking about. And if you don't believe the proven health hazard, just use the WWW for enlightenment.

Here, let me help you with a link from one of the main companies which provides the antennas for the tower:

http://www.hitachi-cable.com/about/c...ile/index.html

And a quote:

Quote:
Hitachi Cable won orders for transmission antenna systems for digital terrestrial broadcasting to be installed on the antenna gain tower on the upper section of Tokyo Sky Tree. More specifically, the Company received orders for four units of omni-directional, multi-panel antenna systems (a total of 640 antenna panels), which consist of two 20-panel omni-directional antenna systems in four stages (a total of 160 antenna panels)

btw
The electromagnetic radiation around present Tokyo Tower was measured.
It fell below the standard of Japan in all measurement point.

Anyway,

Starting this monday the cranes will be taken down one by one. But we still have to wait a bit longer before we can admire the tower without the cranes. The whole process will take until July.
