To scientists that's 10 milli-Siemens. The near end of the wire came up in the shack. That's under my kitchen sink. It's still there. Open-circuit at the far end. Reg, was that 30 meters and 90 feet or 60 feet and 20 meters? Just for us mathematically challenged. W4ZCB |

for us mathematically challenged. W4ZCB =================================== Harrold, To be exact, 30 meters = 98.43 feet. It was NOT a deliberate mistake to check on how much interest would be displayed in the experiment by readers. But it could have been. ;o) I did swap the connections between antenna and counterpoise and, as you can guess, it didn't make a scrap of difference. The underground antenna ended up in a bunch of other radials. But the best radial I have is the incoming domestic water main which is terminated at its other end by 100,000 miles of underground pipes feeding the whole of the Black Country (where it all began) and the Great City of Birmingham (which yesterday suffered a tornado due to Earth warming climatic changes caused by American pollution of the atmosphere). It was only the day before that life in the city was disrupted by police raids on houses alleged to be occupied by unsuccessful suicide bombers. Birmingham, in opposition to Manchester, will do anything to get into the news! ---- Reg. |

![]() the Great City of Birmingham (which yesterday suffered a tornado due to Earth warming climatic changes caused by American pollution of the atmosphere). Birmingham, in opposition to Manchester, will do anything to get into the news! ---- Reg. Hi Reg, I live in the Great City of Birmingham, and there was no tornado yesterday due to Earth warming climatic changes caused by American pollution of the atmosphere. We do have tornados here from time to time and have even before the American pollution of the atmosphere. Of course I live in B'ham Alabama USA so I am closer to the pollution than you are. The company I work for has spent billions on environmental projects as has a number of other companies. It is starting to make a big difference in the air quality over here. I doubt seriously the B'ham tornado was anything out of the ordinary (1 every 100 years). If you want to see who is really cranking out the pollution, look at third world countries who are attempting to progress, which takes energy that they can not afford, much less any pollution control. China comes to mind. Gary N4AST |
