I am new to amateur radio, and apparently have a roof mount antenna on my old plow truck. The coax appears to be in good shape and fairly stout, but the connection appears to be damaged. I was hoping to replace the connection and put it to use but I have no idea what this is and where to look for a replacement and what I will need to connect a mobile radio. I would just Google it myself and save your time, but I don't know what to search for. Can anyone out there point me in the right direction?
