SIGINT people really hate to ask This is the secret radio tower which the government used to intercept thousands of trunk phone lines running through Britain to the Republic of Ireland. The structure was located on the boundary of the URENCO uranium enrichment plant at Capenhurst in Cheshire http: //www. lamont. me. uk/capenhurst/ 2
It is also located right on the microwave line-of-sight between two British Telecom radio towers at Gwaenysgor in North Wales and Pale Heights in Cheshire. The BT towers form part of a chain carrying thousands of phone lines from England, along the north Wales coast to Anglesey, then across the Irish Sea to Dublin. Four microwave channels ran in each direction, each capable of carrying one TV channel or roughly 1, 000 phone calls, using frequencies around 6. 5 GHz. 3
