    Here is a white paper that Bob85 used to get his answer, that was already posted in post 9 of this thread...

    http://bird-electronic.com/en/Resources/~/media/Bird/Files/PDF/Resources/white-papers/VSWR-Measurements-Using-In-Line-Power-Meters.ashx

    I also came up with an answer, and used a different method to get it. Perhaps you should read the posts beyond the first post once again. After all, I see no reason to post what has already been posted in this thread for someone who is acting a lot like a troll.

    You might take into consideration that this isn’t the typical CB radio forum. I understand what you’ve said — maybe why — and recommend that if radio is your interest, this forum may have more to offer than is apparent at first go-through.

    Antennas are a daunting subject.

    Please don’t reply. I’ve shot off my mouth in the wrong way elsewhere. Offended when there really wasn’t cause.

    Yes, but at what feet per second or miles per hour?

    Looks like someone has a chip on their shoulder. That chip has a way of getting knocked off. No need for that kind of post at all regardless. Bob83 is indeed one of the more knowledgeable members on this site and just because you don't understand the problem does not mean he is full of bullshit.

    I do not find antennas daunting, you may be speaking for yourself. I do not hang around typical CB forums or any CB forum for that matter. I am not a troll either. What I like to point out is the needless urge for some people to express their incredible knowledge whilst reciting from a book sewn to their chest. It is cringe worthy.

    Flattop_(Dick_Tracy_villain).jpg This is my opinion and if you don't like it you must be wrong!

    I have had people like you working for me, for the short while they lasted.

    He just made a new record. A few posts and he is on the ignore list already.

    This is the same expert that asked THIS technical question:

    "... That is, do the circuits work in the same way by grounding the pins or what ever?...

    VSWR at the antenna ? A VSWR meter placed in an antenna input ? Who do that ? For what purpose ?

    Let’s imagine that such person don’t have an antenna analyzer with a short coax jumper at the antenna site in order to adjust it , just use the jumper , maybe 10- 20 feet, installed the VSWR meter, connect from meter to radio, hit the PTT and have a friend tell you how much SWR you have. Just make sure you test the antenna close to QTH . With a short coax jumper you will have an idea of how much VSWR you have at the antenna feed point.

    VSWR should not be affected by length of coax cable. Radio signal for sure will. The longer the coax, the bigger the loss in signal reaching the antenna.
