Sherlock Ohms: Antenna Tower 4 Has No Base Current
Sherlock Ohms: "Antenna Tower 4 Has No Base Current" - RF CafeSherlock Ohms is a regular feature of Design News that presents submissions from readers about troubleshooting challenges and how they were solved. This story titled "Antenna Tower 4 Has No Base Current" relates a broadcast station engineer's experience in troubleshooting a transmission cable problem between the radio station and its tower located ¼-mile away. Anyone not familiar with the type of lines run over those distances might be surprised at the culprit. Jim Flinn, friend from my USAF radar tech school days, spent many of his post-USAF years running his own commercial radio broadcast station maintenance company. The stories he has told and pictures he has shown me of some of those installations, which he says is more the rule than the exception, make you wonder how anyone stays on the air.
