    OK, I'm pretty green when it comes to CB's and cables and waves and terminology so I have to ask.
    I bought today a Wilson 2000 antenna and mount it on it's spot. I drive a Volvo so the place I'm talking about is on the passenger side on top of the mirror where there is a cut for the antenna to be screwed on.
    Then I said I'd do it like pros.... so I went back inside and bought myself an SWR/Power meter and tried to follow instructions I saw on Youtube on how to adjust the antenna height and such.
    I followed the steps I saw on Youtube and I was hoping to have to adjust the antenna length based on the readings. But surprisingly from the very first measurements on both channels (1 and 40) the SWR is perfectly equal at 2.6. From my understanding that is high as in every video folks were measuring around 1.2-1.5.
    Please share some wisdom in this matter with a CB noob and tell me if I should be worried or just use the CB with the new antenna the way it is.
    Just to mention my CB is a Stryker SR-497HPC.
    Thank you and every input is highly appreciated.

    Okay.........did you unscrew the stock antenna and replace it with the Wilson?
    If yes that is absolutely WRONG! Stock Volvo antenna mounts can barely handle the weight and wind load of the stock antenna let alone a Wilson 2000!
    Mounted on passenger side?
    Another bad move! Tree branches will have a field day with your new antenna!
    Are you using the stock coax?
    Horrible move, especially with a Stryker 497!
    That is a high power radio that needs a good antenna system! That radio has NO business on a stock antenna system!
    My suggestion to you is a screw in bird perch mount on the drivers side only with a good antenna mount and some good (not truck stop) coax routed properly into the cab. You can use the Wilson 2000,but they are no longer a favorite of mine. Quality isn't what it used to be at Wilson. I use a 5' Skipshooter top loaded fiberglass whip.
    You should also consider running power for the Stryker direct to the battery. It will work off the power posts in the truck, but not recommended.
    Strykers, and other high powered radios are NOT plug and play like a Cobra 29! They need to be installed properly to give you your money's worth and not damage your high dollar radio!
    There are many Youtube videos out there to help you with a proper install.

    These are common rookie mistakes that you have made, but with a little research you can make your system right and be able to truly enjoy your big radio!
    Good Luck!

    I hope I wasn't too harsh! I just hate to see a guy/gal spend their hard earned money on a big radio and be disappointed with it or,worse, damage it! Getting stuff right in these newer trucks can be a little frustrating but when you get it right it is very satisfying! Although...........it will never be absolutely perfect! Just the nature of the beast!

    You were not harsh. You just said it as it is.
    Now I saw in the link provided that coax cable is 15 feet long. I know that length is needed but I need to know if there is any particular way of rolling/folding it when I install it.

    You can get longer or shorter coax depending on your needs. Try not to coil it if possible. If you can get to a Radio shop that does installs it might be a big help and time saver for you. If not do some research online and Youtube and you can probably find the info you need. @craig_sez has some pretty good vids on Youtube regarding installs, although mostly regarding Cascadias,but many of the same principles apply. This is also a good thread on big truck installs!

    He can get into the weeds a little but there is a lot of valuable info on big truck installs.

    Yea with a strong cb unit using the stock coaxial on out setup is like putting a v12 in a car with a single half inch exhaust.
