I looked around the site all day and haven't found and threads about using a Am/Fm antenna as an antenna on my car. I have some aftermarket antennas that say they are for am/fm and can also be used for CB. They are 32" long of the actual rod and has a spring base. I am a licensed ham radio operator. The antenna was given to me for free. So I thought maybe i could use them as an antenna for my scanner or maybe my handheld radio external antenna. Please let me know if this would work. I do NOT have access to an SWR meter.
