No, not inside the transmitter rooms. They were well shielded. The copper pipes you see in some of my photos are actually huge coaxial interconnects, which are brazed and well sealed to prevent loss. I have for sure experienced that on the roof of First Canadian Place however, which also has some massive TV transmitters on it as well. I've even noticed instant slight ocular headaches when looking at such antennas at close proximity while they are in operation.

It is however interesting being up there in a lightening storm. The building rumbles whenever it is struck.
