    Im either haven a major brain fart or something im just not seeing...
    Heres the scoop..

    + probe on center pin of coax and - on the gnd side(with antenna still attached on other end)and i get nothing on the multi meter(as if i didnt touch probes)..
    Gnd to gnd and then it reads all zeros...
    Antenna bracket itself with gnd probe and postive probe to top side of ant stud and it reads 000 for a second then goes up to approx 118 ohms...
    On tje center pin of coax to top side of antenna stud i get 2ohms but that # floats a bit cause i cant get them probs to stay in place very well..

    I do the same but with one probe on bracket and other on the threaded gnd and all zeros...

    I now move over to my analyzer and my resistence reading(r# depending on freq)goes anywhere between 42 ohms to 52 ohms but my resonance points(x#) are 5 or less off zero...

    What am i not seeing cause it seems my range is dwindleing...

    Weather here in eastern canada is still crap so not much i can do till it gets better but what in the name of god am i missing..

    What kind of stud are you using?

    Does it have a phenetic or nylon insulator?

    The word is Phenolic, it is a resin thermoset plastic used as insulators in antennas. I have a crap load of studs with these types of insulators, they are older ones but nevertheless the nylon insulators don't hold up as well.

    The ipad keeps correcting words when I post my comments.

    Take it apart, clean it up, and put a very thing amount of silcone adhesive or sealant on all the items (Except the where the antenna mounts to the stud) to make sure they are sealed on the mount.

    It sounds like there is moisture in the mount itself.

    Do you have a hair dryer and power for it?

    Try slowely and carefully heating the stud above the mount and antenna up and see what happens.

    Since it's still winter weather and it looks like salt on your truck and antenna (or it's just muddy water from the road), it looks like you do have a corrosion problem. That would definitely cause the numbers to change.

    Craig, on second thought, maybe if you wash your truck, the numbers will go back to normal. Ha ha.
