    1/4 wave tuning frustrations

    Hello All

    So i have a set of 1/4 waves spaced 74 1/2 inches apart ..and i cant get any better then a 1.4 swr.. i tried all combo's ..1.4 is the magic number.
    Strange thing is i tune the driven stick to 1.4 then install my reflect stick... it doesnt change anything. no matter how high or low it is.
    Observation... i have a shorty antenna from Noisemaker.. with the reflect stick .. its 1.1 R55 x-0.. and works very well..
    So with a tall 1/4 wave driven stick i cant get it to tune. What are the characteristics of too short spacing?. Do i need to go wider spacing with the taller driven stick?

    Thanks In Advance

    Do it!! Lol. Heres a dumb thought. What if u isolate the hitch and tap the ground right at the base. I can make u an insulator 5" x 1.25" thick. Would have to lower the arm a few inches but is worth a try

    Meaning tap the ground right to the 3/8 24 stud?.. if so thats how i have it. i see what you mean the insolator to get the antenna seperated from the mount...correct?

    right- but its also grounded through the hitch - theres no isolation. Screw the insulator into the mount and then tap your braid between the insulator and the stick that way the arm isnt adding length to the stick (cause technically it is right now.)

    just thought of this too - the mag mount may also be the culprit - you have a capacitive ground and a physical ground going on - even though the rear is grounded to the mag mount - the mags are making a different ground and that may be bugging it out.
