NGC CB radio question
« on: Today at 09:11:41 PM »
Do RVers use CB radios?
I found this in my Dads stuff, he was both CB and HAM radio guy, can you tell me what kind of base this is, CB? I found a whip or actual antenna part separately but it will fit, it's 48" long, isn't that longer than a CB wave? If the base will work can I cut the antenna to correct length? What is optimum length for CB?
I inherited the radio too.
I don't think the magnet will work on my RV roof, it's not metallic (I don't think) just use the hood of the E450?
Thanks for any reply's

A standard CB antenna is 102. You have a loaded antenna and could be CB or 5/8 wave 2M antenna. Use at minimum an SWR meter to check it with your CB. If not setup right you risk damage to the CB.

I don't know what frequencies the US CB is based on I understood it was around 27MHz. The formula for an antenna with a ground plain is (1/C,meters per secound) x Frequency in Hz this will give you wavelength for half wave x.5 quarter x.25 and or 5/8ths.

Now here is the messy bit ground plain is approximately the half wave length there is a possibility you have a ground plain antenna base (often GPI on marketing guff) this has circuitry that allows you not to need a ground plain but also affects the cut length and the manufacturer of the antenna should provide a cut length for the various frequencies.  The feed coxial/cable should also be a function of the half wave length, the good news is a lot of antenna suppliers when they sell an antenna for a particular band all this will have been worked out and done for you.

If it doesn't work before you toss it you might get lucky and find its the same type of CB used in a TV show like the A-team or the Dukes of Hazard or the original road warrior where people building replica vehicles seek out a particular make and model to complete the build.

  Hey Foto,
    Yes , RVers and Truckers still use CB radios. That antenna is known as a mag mount base load antenna and works great when tuned properly. I would get a piece of steel angle to mount to the side of your roof rail and stick the antenna above the cab area for best coverage. Your hood is probably fiberglass so not magnetic.
    Google Radio shops near a truck stop in your area and they will be able to set the SWR's to match the antenna with your radio. That Midland radio is one of the better ones for it's time . 10-4 good buddy :evil:
