Reddit mentions of Astatic PDC1 100 Watt SWR Meter

All you need to get that distance is a properly mounted 102 inch steel whip with a heavy duty spring, the mount should be drilled directly into the body of the vehicle and as close to the center as possible. The closer you get to the corners the more directional your range will become (I.e. back left corner of the vehicle will send the signal further off the direction the front right is pointed) this can be a good thing for vehicles falling behind the caravan. Get the antenna as high as possible the lower and closer to the body the less output you will have you want everything you can get for this range. Any other antenna won’t provide you the results your looking for; period, point, blank. That’s the first most important step. Get a clamp down if it’s too tall.

Next use proper coax RG213 it is lossless and 50ohms this is the perfect coax for CB radio; same stuff used by military. This is also important for this range. RG 58 will have loss and could be the difference in a mile or two.

You will also need an amplifier. Just a KL203P will provide you the power to reach 10 miles it will pump out 100 watts. They are very clean using a mosfit and don’t bleed over on other channels and cheap. Also, be sure to get an amp with a preamp this boost your receive to pull fading signals in it will help insure you get the 10 mile range.

If you have done the above steps you can now buy just about any CB you want they all put out 4 watts. However, you can get them peaked and tuned to match your amp for a little extra distance a local shop can do this or online shop like Bells. However, it’s not mandatory with the above amp and you’ll still get 10 miles.

If your installing yourself you’ll need an SWR/Watt meter to ensure proper working condition and you don’t burn up your equipment. Although, you can always have a local cb shop set it up for you and install.

Lastly, you’ll need to stay on off channels when operating so if you start hearing skip or DX turn to another channel that’s quieter. Stay off 6, 11, 19, 26, 28, and 38 these are frequently used and your transmission will be hampered by that. SSB will allow even further transmissions but be sure you amp has SSB capability KL203P does. Also, keep in mind that SSB requires each radio operator to tune in the one being received this is why it fell out of favor case driving and tuning is a pain in the ass. If each vehicle has a passenger this would not be an issue though.

This setup will get you 10 miles city, county, woods, mountains, and 20 on a flat plane. Anyone who says otherwise don’t know what they are talking about. Caravans are popular among over the road truckers who use this method. Also, keep in mind that rear vehicle only needs to reach the middle vehicle as they can relay the message to the front vehicle or vice versa.

I’d get the Uniden 980 SSB as they are matched for the KL203P stock out of the box. Many people run these without the peak and tune with awesome success.

You should always tune the antenna. You will need a SWR meter to make the adustments.

I keep this one in my Jeep for when I hit something and need to check tuning:

It will get the job done.

The Uniden 520 is a great choice for a basic radio. I've been using one for years with excellent results. It's really hard to beat for the size/money.

Consider the K30 magnet mount antenna for an alternative in that size.
I've used both it and the Little Wil and found the K30 to perform noticeably better. It's also less expensive:

The other commenter that suggested getting an SWR meter is also correct. These antennas all require some degree of adjustment for optimal performance. Just a basic meter will work fine.

And the jumper:

The meter and jumper is something you'll very rarely need (just when moving the setup to a different vehicle, for the most part) so if you husband has a friend into CB or HAM operation, he may be able to borrow one for a few minutes rather than buying.

Finally, you'll need some way to power the radio. The easiest way is with a lighter plug:

Just cut the connectors off the ends of the wires and splice it with the ones on the radio.

Alternatively, you can connect to the fuse box with an Add-A-Circuit. These come in different sizes depending on the fuses in your car. You can get one of these for less than $10 at any auto parts store.

This is what I have

the only other thing I see that you should consider getting is a swr meter

http://www.amazon.com/Astatic-PDC1-100-Watt-Meter/dp/B004ULN610/

when your dealing with low watts system like a CB matching your antenna to the CB can make a major difference on your transmit and receive, as much as a few miles.

Forgot to mention...

A good SWR meter is always advisable. Never trust the radios built in SWR meter.

SWR is short for, Standing Wave Ratio. It's basically a measurement of resistance from your radio thru the cable and thru the antenna. You adjust your antenna by either lengthening it, or "trimming" it down. The Solarcon A-99 antenna has tuning rings to make this process easier.

Here is a good link that explains more on this;
