    Thanks Turbo & Squirrel... Been busy with work so I have not had a chance to work on this issue.

    I am using the 36 inch whip that came with Lil wil. I did calibrate the meter and tried moving antenna around... the Wilson web site actually suggests certain vehicles such as Suburbans/Excursions may be best served with antenna centered toward the front of the roof (6 - 12 inches behind winshield) do to problems with the roof rack mounting strips causing possible interference. I tried that with no luck. Time to take it to a professional and get it done right.

    as to mounting it between the roof rack i had no idea wilson recommends mounting it in front of it. i put it in the middle did some minor cutting and it worked just fine

    Trim the whip down some. I've got three Lil Wil antennas, and all three were running high SWRs until I trimmed approx 3/4" off of them. Now, all three (on a '89 C-1500 & '01 Jetta) are getting 1.5 across all channels.

    If you do trim, make sure to stay 1/4" at a time, as tempting as it would be to cut more to get the process going faster!

    redmule, Don't know if it would help. But grounded my cox. from the back of the radio & got my swr's down to 1. give it a try, don't think it will hurt

    if yor swrs are high on 1 and 40 you most likely have a ground problem

    also theres some misinformation here if your swrs are higher on 1 you have to pull the antenna out if its higher 0n 40 you need to cut it a little bit 1/4 inch at a time if its 3 or above across the board its most likely a ground problem hope that helps

    Also check the coax. If there is a cut in it or an end is damaged than can also mess things up.

    Are you also calibrating the radio to read the swr?
    Depending on the radio you have to switch to calibrate mode then after you calibrate the radio you switch to swr mode.
    I believe some of the Unidens and Cobras are like that.
