I think "Doc gave you some limited information explaining something about those possible issues. Just reading it here on the forum however, may not give you a through understanding. You will probably find that some Wilson mobile antennas will correctly show an open circuit with your OHM tester while others will show a shorted circuit. Sounds like you are talking about a Wilson 1000, 5000. When reading my 1000 physically at the base of the coil, my 1000 shows continuity between the shield and center conductor. It would make you buzzer go off. My position now is, I like Linearone's answer best so far. I think he was making a special point, without really saying. This came about after re-reading your post. It is because of the way the way you posed your supposed dilemma. I can just bet that you have been listening intently to some in the big swing, big power, big antenna, key-down bunch. No doubt some of those guys may really know what they are talking about, but I wouldn't hold my breath waiting for the real truth about a lot of ideas they hold. Listening and talking their talk is not a problem, as long as you keep a mind towards real understanding and not just assimilating some pumped up hype about this or that. You should slow down and get control of your OCD. That may be the only problem you have right now. You can't go Will-Nilly, and start cutting off pieces of coax and expect to define a problem or develop understanding with your testing, comparisons, or experimenting. After telling us your coax was bad, then telling us that you found out a part of the segment of coax was good---does not explain what the problem was. In fact, you did not have a problem---except maybe in understanding. I miss-read your original post, as being a question about a problem. I have read Tom Sawyer already. |
