FCC viewing restricting guyed towers
The Federal Communications Commission is considering numerous conservation groups' requests to restrict guyed towers from being built as well as limiting tower heights to less than 200'.
Some say that these requests will not be acted upon; others caution that there are extremely powerful avian lobby groups that have the political clout to get the FCC to move upon their requests and that the rules will severely interrupt the build-out of the nation's communications infrastructure.
You are invited to let your voice be heard FCC prior to the FCC's January 22, 2007 deadline.
