Your welcome and I'm happy this thread answered your questions. That is what this forum is about, helping each other out. So many in here has helped me so it is good to pass it on. Looking at your picture post I see you have the older style original antenna with the wire style element at the base. The new ones have changed to flat sheet metal instead of wire style. But they are suppose to be electrically the same. Good luck and happy DXing!

Believe me I was happy to see your info. I was about to order a new antenna. I found the installation instructions so now I have the exact measurements to tune this in correctly. I put it up and messed with it for about a week trying to get it tuned then gave up, that was about a year ago. Thanks again!

The top section of the whip is all you move up and down to adjust the swr and if you take your time and be picky it should give you a great swr reading across the 11 meter band. But like they say it can vary just a little because of your situation, and make sure you seal off your coax connection because it it exposed to the elements. I put heat shrink tube on mine. Good luck and let me know what your SWR ends up!
