Andrews 4,6m

It seems to me those actuators have some high power motors on them and consume as much energy as a major household appliance. What kind of cabling are you going to do with the foundation? Internal conduits or all outside?

I cut the hole in the metal plate. Will let plastic pipe ~75mm (red lines) go through concrete and enter inside pedestal mount. I do not care about electricity consumption.... as will turn antenna very very seldom, and also possible to turn it by wrench, I mean mechanically.

That's gonna be a hoss! :hatsoff

Central metal part and pipe for cables are in place. Soon will start to weld some metal bars and angles inside the hole.

Andrew pedestal mount is moved to the installation site. Quite heavy stuff I must admit :coco

Did some preparations before filling the hole with ~5m3 of concrete. Welded every crossing of the metal, so construction is pretty solid right now.

Very nice work! I'm liking how this project is turning out

I would put some eye bolts in a couple of strategic locations to use for winching points and tie downs when working on the dish.

RimaNTSS · Jul 16, 2016

If I need eye bolts I can add them later to existing platform. But, by now I do not see big need for winch, as I was removing this antenna from previous location without any winch, and I think I will be able to install it back same way.

Have filled up hole with concrete. Looks heavy

Will let it dry for several days.

I estimate it to be over 10,000 kg

Will take a while to cure. I like it. Did you mix your own or get a truck load?

RimaNTSS · Jul 19, 2016

I was told it is about 12000kg. If was mixing myself, I would be still mixing till 25th July :biggrin

. Of course, truck came and filled it up. That is why I digged couple of holes in the ground 50cm wide and 125cm deep to use any possible left overs of concrete. Those 2 holes are also full with concrete now. Will use them for stand-alone antennas, of course. :angel2

Have some updates on the project. Pictures should be enough?! Friend of mine (actually neighbor, whose house is seen on one of the pictures) helped me to erect the mount.
