I think that the idea of sharing masts is actually quite good and appears to have been succesfully implemented in other countries. From a society point of view i cannot really find any reasons for why every company should have their own towers to cover one and the same area. I mean why should there be seven masts in close proximity where I live instead of one. I still have a very bad reception at home so I am better of using the old school wired phone instead. And as long as we also have cable connection to households we have some redundancy and this should be satisfactory for the average person.

Unfortunately the argument presented by the greens in this case are rather dim however so that in its own right is a shame as they obviously have not done their research very well.
