Anyone on the reflector had experience burying unshielded twisted pair wires at HF frequencies?.
How much loss? Estimated ? Measured? When burying, was there a before and after common mode increase ? Notes At audio frequencies the phone companies used to run many twisted pair in lead shields. In Radio stations, where I was employed, shielded twisted audio cables were used in high RF environments successfully. Thanks in advance for replies. 73 Bruce-K1FZ www.qsl.net/k1fz/bogantennanotes/index.html _________________ Topband Reflector
