Hello Cajun Invader:

Give Steve a call (661 256 6976) he has answered many questions on antennas and there installation. Ask him to give you my phone number and I'll talk to you also.

Any one whos says their an expert on antennas is lying to you!

We go ahead with antennas after a long and involved testing period, and put our money where our mouth is in buying the materials and selling the products. We also believe that helping out a customer is part of the job.

Added 6 Feb 09: Hello CI I must not have read all your posting or didn't get all downloaded some how?!??! Yeah I'd say your installation is working. Yes the I-max 2000 and the I-10K will show a short or continuity between the center pin of the coax and the shield wire. This short as some call it is the connection of the T2 Trombone Tuning Hoop connectiong to ground. Which is how the I-10K Antenna is designed. Its OK!

We get a lot of questions on how high the a antenna needs to be, we answer the higher the better for antenna performance. But at the same time you don't want the antenna to be to high to be unsafe and fall into power lines of the neighbors new car.

Again feel free to call.

I really hate to ask so many questions but I am bound and determined to learn about antenna theory.
CI, "Yes" you are correct: the Imax should make your buzzer go off. 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.

You are exactly right, I was being feed wrong information and as always that is why I came to the WWDX seeking the truth. Bob-85 took the time to explain antenna theory to me in detail and gave me some excellent reading material.

I used to think that it was all about the watts. No I see it's more about how you deliver them. You might be able to fool a meter but you can't fool mother nature.

Thanks for all that helped me with this. As Marconi said, it was all the OCD. I was actually 10-8 the whole time.

Well CI, I was concerned that you might take my words wrong and develop a bad attitude along with the OCD. It is refreshing to still find young fellows that don't take offense at being fussed at a little bit.

You can't go wrong listening to Bob.

If my words ever really hurt anybody, then I would figure out some way to make a living at it.

Thanks for hanging in there,

Marconi
