Have we figured out how they plan to instal the antennae on the missing row?

This also makes me wonder about the construction of the interior of the spire. I would imagine that it must have some kind of stairways installed within that interior space which might allow workers to position the missing antenna in place as long as the cranes are still able to lift the equipment to that height. It's just a guess on my part so if anyone knows the facts of the situation without having to guess like I'm doing I'd also be interested to know how they're planning on doing it.

Im guessing that it will be full of communications electronics and satellite dishes on the antenna

Only way I can see is by jacking up a crane. Otherwise, by helicopter - but that would be quite tricky.

Just my 2 yen...

I was thinking via the crane and then installed via the inside. But all these maneuvers seem difficult.

It was stated earlier that they simply didn't have the antenna to put into that spot when the time came to install it as opposed to just having an empty portion of the spire. I tend to think that they'll finally get it done but now that I see how much the spire has risen it makes me wonder how much taller it can get before the cranes won't even be able to reach that height. They're very ingenious though and because the renders shows the entire spire covered with antenna I think that's the plan and they'll figure out a way to do it.

The spire already grew too much for the cranes to reach the missing spot with a load.


02/25 quick blog update:

Previously I had asked why the top of the tower was built so strongly. The diagonal beams that hold up the outer edge of the top platform appear much stronger than necessary for people walking around. Your question triggered a possible explanation.

Perhaps people and equipment can be lowered or raised from cables hanging from that top platform. The concept would be similar to window washer hoists installed on many modern skyscrapers. It would allow for maintenance of all those antenna arrays.

In addition the cranes where using a equilibrium hoist in order to put the antenna into place due to the difficult angle , if I'm correct in order to install the missing part requires both cranes to be raised up or one by one in order to do the missing job , only one crane can't install the full 360 degrees antenna equipment.

I'm assuming that you're referring to the very top of the spire. The reason it's so big is because that's where the two mass dampers are located which are intended to stabilize the spire if there's high winds or an earthquake. It's an interesting thought though in terms of how that missing section of antenna might be installed but it certainly wouldn't be easy. Since Momo has informed us that the cranes are already unable to reach that spot they're either going to have to leave it empty or figure out some ingenious way to do it without cranes.
