    If you look above what i wrote you will see that i am agreeing with The DB. Yes means he should answer the question and stop going around the questions with irrelevant answers. So to answer your question Yes.

    Db that helped Thanks. \\ Yes that is how we benifit and Learn. Maybe he will answer. Tony

    Db that helps. Thanks. Is the grid dip meter a better way for finding resonance ?

    CTR you mentioned one THING. The subject is field strength. You had mentioned earlier that applied power and FS was certainly a better way to test for efficiency. Will you explain the proper way of tuning a mobile antenna via FS. ? Tony

    In most cases the use of feed-line SWR alone to indicate antenna efficiency is invalid, because SWR indicates only the degree of mismatch, not efficiency.

    Db I would like to see your view on the conjugate match and maximum power transfer. My understanding is the system as a whole is resonant. This is when matching at the feedpoint of the antenna accomplishes 50 ohms at the source and at the antenna for maximum power radiated. This is why...

    Thanks for posting CTR . good to see you back. Since you have educated us on swr and meters, My post about reactance being wrong. I think i should have posted impedance matching. Maybe you can enlighten us on the benifits of matching, Tony 73

    Db i am waiting for CTR to respond to your comments. I assume he is busy. You made some very important points. Is his credibility really valuable ? I would have though so .... Tony 73

    What type FS meter do you use ? (6) If a suitable matching network cancels all the reactance developed by a non-resonant-length radiator and a random-length feed line that is mismatched at the antenna feed point, the antenna system is resonant, the mismatch effect is canceled, maximum current...

    I had the same thought Rm 71 . I have not had time to do further testing. There are so many variables in every situation. In my situation lack of ground plane is the biggest problem via vicegrip pliers mount , not enough metal underneath the antenna . That is because the high losses in...

    Very good. I by no means am playing you off what ctr stated above. I am just trying to Learn. I agree with what you and m0gvz said earlier. I and others are not on the same level. as you 3 are. I believe you all have good solutions , But at the same time it has to be simplified to a...

    M. Walter Maxwell said: THIRD, we should become more familiar with the universally known, predictable behavior of off-resonance antenna-terminal impedance and its correlation with SWR. This knowledge provides a scientific basis for evaluating SWR-indicator readings in determining whether the...
