Preface: I have an Amateur Extra license. This is the most technically demanding class of license issued in the Amateur Radio Service. I am primarily interested in using radio as a tool rather than a hobby and, as such, have focused on the technical aspects of making it work as well as physically possible since my primary goal is communication in adverse conditions.
I can't provide you a direct link to this thread because the forum is down for maintenance, but google "NASIOC Let me see your CB radio". It's a thread on a car forum I'm part of. There's a tremendous amount of information about putting radios in cars in that thread and it'll save me a lot of typing if you just go look.
ETA: I think This Is The Right Link
but I'm not sure because NASIOC is still puking all over itself.
I mentioned this above, but did not get any response regarding this issue.
I really do not like the way antenna cables run along the rood or the trunk of my car.
I would rather have something like this.
Can anyone comment on this? Pros/cons? which to buy? where to buy?
That's a horrible setup. I say that for a number of reasons.
First, the antennas commonly employed on cars are almost all either 1/4-wave antennas or clever designs that try to fake being 1/4-wave antennas. All of these fall into the general class of being monopoles. The critical lesson to draw from that is that you can't radiate with a monopole. You have to have two poles working in opposition. Basically, you have to have a dipole. Since a 1/4-wave antenna is just one half of the required dipole, your car becomes the other half. This is why placement on the car, and mounting method, matter so much. Think of the car as a mirror. The antenna forms one "stick" of the dipole and the mirror image in the car forms the other. To make a good image, you need a large (1/4-wavelength, minimum), flat, unbroken, solid metal mirror. If you somehow fail to provide this "mirror", the signal is distorted, just like looking into a broken, warped, or cloudy mirror with your eyes. Because of this, the antenna mounting solution that works best is one that is mounted dead center IN, not on
the largest piece of sheet metal on your car. Anything else is showing up with a knife at a gun fight.
Second, it's using screw-tightened "pinch" mounts. They're hugely inefficient. Again, you're bringing an airsoft gun to a big game hunt.
If you want a better/cleaner install, you want to put an NMO mount in the center of the roof. Inside, you run the cable over your headliner and then down the inside of the car to wherever your radio is. You never see the cabling. I tried to post pictures of it, but the forum software refused to let me do it since they've more than 850px high and I'm not going to resize them just for ZS. You can go to the thread on NASIOC and see them full size.
If that picture of the VW is a picture of a CB setup, it must be some sort of dipole array, and looks expensive.
1) That's not a dipole. Dipole has a very specific meaning in the context of antennas. That's a phased array. Specially, CBers call the one they use that looks like that "co-phased antennas".
2) Those aren't CB antennas. They're too short. Even with serious loading (and the bases aren't big enough for that), they're still too short to be resonant on 11m.
Again, please google for that thread on NASIOC. There's so much information there that I've taken hours to type out over the years.
