Lancer, I'm aware of that. It's too bad that most of that discussion deals with misconceptions. 'Doc Doc; Which misconceptions? |

Don't 'read into it' any more than what's there, especially about the 'normal' trash that goes on in this NG. 'Doc I read exactly what you said............. Something about dragging out misconcepts. It seems to me that you may be the one that believes in misconcepts. There is a easy way to determine this. It's done by asking you a simple yes or a no question. Do you believe a shorter antenna can be made to show more gain than the 102" SS whip.? yes or no I bet the results of your test were unrepeatable. I think your X-terminator generated a minor lobe in the direction of the recieve antenna due to the coils and a funky RF ground and other variations in the pattern. I think he fudged the numbers. Like I said, if anyone has one of those X-terminators in my area I'll be more than happy to run a test. In fact, I can run it with a few other CB antennas I have laying around, including 102" fiberglass and magnetic SS whips, a short center-loader from RS, a couple helical dummy-loads, and I even think there's a rubber-ducky in the scrap heap. And I can test them properly, mapping a field from my truck to just outside the near-field, using an unmodified AM radio (unmodulated), no QD connectors, tuned with an FSM, measurements for forward and reflected power, and DC voltage measured at the radio during transmit. Hell, I'll even punch a hole in the roof for this test! It would be interesting to see the 102" fiberglass against the S/S whip. |

Gain in relation to the 102" SS Getting back to the misconception aspect.................... You said yes to "Can a shorter antenna show more gain than the 102" SS. Now the final question. Where's the misconception I am spreading? You are spreading the misconception that your tests are accuarte and the results are repeatable. My tests (plural) were made as accurate as any CB'er could do with common equipment. Are you suggesting only professionals with professional equipment and a test range or chamber test antennas? Are you suggesting that we just read the book and leave it at that? My tests were accurate enough to show a consistent gain ranking of the antennas. Even though one test showed a different reported ranking between two signal readers they were still repeatable in the sense that each time the 102"SS was compared to others it fell short to specific antennas each and ever time. You seem to forget one thing. I originally tested the X-Terminator to de-bunk it. I could not. I could of just kept my mouth shut. I am sure others in this group would of done just that, but I decided to post the numbers anyways. The numbers don't lie. Where's the misconception? I never suggested a tolerance to the tests. I was up front and detailed about the conditions. All I did is post the numbers. What's accurate?...........The gain ranking What's repeatable?.............The 102" stainless being beat by some shorter antennas. Ther's no misconception. |

Thanks Doc....I have a couple layine around...I might try to shorten one of

If it's near as good as the 108"er, I'll be happy. Thanks for the tip. Tnom. If you get the opportunity to swap the 108" SS with the X-Terminator feel free to report the results. One way or the other. I'd love to see someone else do a test. Be forewarned. If your results are in favor of the X-Terminator you'll get flack for reporting the results. Your test will be examined and will be deemed as being flawed. If your test shows the 108" SS as the superior antenna then the obvious will happen. Your post will be accepted as legit and there will be no argument over the results. Even though the test parameters were the same. |
