Nacka TV Master
I like big stuff, and this takes the price if you count hight.

There are two of this 300 meter mast's outside Stockholm, brodcasting TV and radio.

They have an Effekt of 1000 kW ERP for the TV, and 60 for the radio.
The cable is thick like my arm.
When I was there and looked at the mast's I saw this larva on the rood. =)
Yeah yeah...
