Indeed it is.
These high rise buildings are used by telecom and several other organisations.
So we were happy to be able for a small price to put up our stuff there.

We live in a flat country here, so the range of the repeater with the antenna so low is 50 miles radius easy.
Using diversity reception with 2 other reception points in different cities gives us a perfect reception and good working of the repeater.
The heart of the repeaters are 30 year old storno repeaters, just the front ends have been modified.
Control hardware homemade as is the software.

Another pet project for us.
