    So I've been running a Wilson 5000 mag mount on the trunk of my company car for 6 years now. Just got a new vehicle so I decided to go with a trunk mount that was a smaller profile then the Wilson. I ordered a new K40 off E-Bay and it arrived this morning.

    I then spend about an hour mounting it to the trunk, fishing the coax behind the rear seat and along the right side of the car hidden away. Even zip tied it all up nice and neat. So next I mount the stinger and go to do the quick 1/4 turn disconnect to test it out. The coil just turns and spins, it never tightens up like it should and it won't detach. It's a defective piece of junk. So I send the E-Bay store an e-mail and they will take care of it but it sucks because I now have to remove it from the car all over.



    I get on the K40 web site and call their 1-800 number listed on their site and on the paperwork with the antenna. This person tells me they sold the rights to the antenna's to a company called DAS. I call DAS and the lady transfers me to "tech support" and I get a recording and leave a message. So far no call back or anything.

    While still on the K40 web site I see a dealer locator tab so I click it. I find out there are two local K40 dealers so heck maybe they can do a warranty swap. I call both of them only to find out neither stock cb antennas, the one place has never even ordered one and the other didn't know K40 made cb antennas. They are all about custom installed remote radar detectors and laser shifters.

    At this point I might just clean up the Wilson and slap it back on the trunk. I'll see how the E-Bay store plans on resolving this first I guess. Sure wish there was a quality trunk mount antenna made. Obviously the glory days of the K40 antenna are gone for good. I don't hear good things about new Wilson antennas either.

    Those have been around a long time. Maybe someone here has experience with one. :)

    The Wilson 5000 magnet mount should do better than the K40 trunk mount. The K40 isn't a bad antenna but the two little alan bolts just don't do a very good job of making a good ground through the paint. Also the K40 can't handle very much juice. I ran a K40 for a couple of years and it worked fine but I found that the big Wilson mag mounts did better.

    FWIW, i have used the Taurus antenna mounts. Sure they don't have any for the quick release type of K40 antenna; but for standard mounts, they work pretty well. Bought a mag mount to replace a Wilson 1000 mag mount. The price was reasonable, they use decent materials (coax was decent too), and it worked out just fine.

    Just saying . . .

    If you are going to mount it on the trunk you want to be bonding the trunk to the main body (which you should be doing anyway :D ) in order to improve the efficiency of the ground plane.

    Something like this which you can make up out of flattened braid from RG213. You should find you need to retune the antenna and that it will need shortening.
