I had an AM transmitter site that had a Faraday cage as the main transmitter hut. It was a three tower array with the TX located in the middle at the center tower. The entire building walls, ceiling, and floor was wrapped in 1/4 inch hardware cloth screen. Besides the AM transmitter the building also housed a generator, VHF/UHF receivers and lots of audio gear as the site was part of a network and the audio program was picked up there and sent via land-line to a remote studio for when we were not carrying network programming. This helped to reduce RFI problems as well as vastly improved lightning protection. It was shielded so well that cell phones would not work when the door was closed even though you could see the cell site a few miles down the road. When using VHF or UHF hand helds to communicate from the main building out to one of the other towers you had to leave the door open or signals were real crappy if even existent even with five watts and only 400 feet between them. Even the air intakes and outlets to the building were screened.

[QUOTE="Captain Kilowatt, post: 548748, member: 39"] I had an AM transmitter site that had a Faraday cage as the main transmitter hut. It was a three tower array with the TX located in the middle at the center tower. The entire building walls, ceiling, and floor was wrapped in 1/4 inch hardware cloth screen. Besides the AM transmitter the building also housed a generator, VHF/UHF receivers and lots of audio gear as the site was part of a network and the audio program was picked up there and sent via land-line to a remote studio for when we were not carrying network programming. This helped to reduce RFI problems as well as vastly improved lightning protection. It was shielded so well that cell phones would not work when the door was closed even though you could see the cell site a few miles down the road. When using VHF or UHF hand helds to communicate from the main building out to one of the other towers you had to leave the door open or signals were real crappy if even existent even with five watts and only 400 feet between them.
