Question about Radio Communications
My CB picks up better is the PL259 is only inserted, not screwed onto the back securely. The antenna is a trunk mount K-40. I have pulled the antenna off again, there is no broken coax. I also ran a ground wire from the mount to the chassis, but this did not help either.
Pitcrew, does the noise go away when you screw the pl259 down tight? Find someone talking on a channel and do the PL test again and see if their signal disappears when you screw down the PL. Have you done an SWR test yet? Is this a fairly new antenna? If this problem came into my store, the first thing I'd do would be an swr test, the second would be to test with a volt/ohmeter from the center pin on the PL to the metal stinger to make sure there is a connection.Then check from the trunk mt to the outer ring of the PL for connection. Now, if you check from the center pin to the outer ring of the PL you should not have connection! If you do, the coax has a short in it,,,
Is this mounted on a trunk of a car? Sorry for all the questions, but there are so many different things it could be, and I'm just trying to narrow it down for you. Hope this helps some, let me know,,, Mechanic
