Well...since I cannot post in the off topic area yet, I will post my question here.

I am trying to figure out if something is possible.

I am looking into getting a CB for my travels for bear reports, help, and just general BSing. I have a good mounting place/idea for this mod (once started, I will start a thread on that).


I have seen an item that you can use on a CB antenna to make it usable for both CB and AM/FM. It is supposedly the only way you can use an antenna for both uses and it requires some adjustments on the unit itself to get the best signal for both. That is all peaches in cream in my book.

However, this is where my first question comes in. Would a CB antenna fit into the normal antenna spot (threaded screw spot)? If so I would just replace that antenna with a bigger one. I am looking at the Lil' Wil antenna. If there is another antenna that works better for this purpose I would use that.

Next question deals with GPS. I also have a GPS antenna on the driver side rear panel. Is it possible to combine ALL functions into one antenna? ...or is the type, strength, etc of the signal too far apart to be functional?

If so..can someone please explain the differences in all the signals?

 

the GPS deals completely with a different signal and will not work with AM/FM... nor with CB.

i haven't seen an antenna used for both CB and AM/FM before and i doubt any adjustments can be made easily to a headunit... i can look more into that later.. but never seen it happen before.

and very doubtful it'll fit.. but yea, very likely it won't work well if it did.

 

They do make a product that you can use a CB antenna as a AM/FM antenna also. It just requires you adjust a few levels on the product itself.

I was doing some more research on this...
CB is in the 20 Mhz area..where as GPS is in the 1000+ish Mhz range.

I guess if I can fit a CB antenna into the stock antenna spot I would be happy.

 

Here is the product:

The Match Maker is the perfect accessory for people who want to use their Firestik CB antenna for their CB and AM/FM radio. Although there are some matchers that allow you to use your AM/FM antenna for CB, be forewarned that your CB performance will be at best, very poor. Unlike the receive only antenna needed by the AM/FM radio, a CB needs its antenna to be resonant within the CB band. Tuners that allow the AM/FM antenna to be used for CB bleed off power to keep the CB's output circuits from literally burning out. If you only want one antenna, than the only wise choice is to use a CB antenna and the Match-Maker. Installation is easy too! Simply disconnect the antenna coax from the CB and screw it on to the Match-Maker. Then, screw the PL-259 lead to the CB and put the pin-plug into the AM/FM radio's antenna input socket. Both coaxial leads are 18" (46cm)long. The Match-Maker has dual tuning coils and the tool and instructions needed to optimize the performance of both the CB and the AM/FM radio.
