This just isn't my week. So I get my CB installed, just like you fine folks on here have in your pics, and I go to syncro everthing and the antenna stops adjusting on the meter. So if any of you CB guru's are out there, please tell me what the hell I'm doing wrong.
I have a fire-stick (4' or 5') with 18' coax, Radio Shack (may be fried now) minni CB and a radio shack meter thing to adjust the SWR.
After I calibrated the radio, I went in to adjusting the SWR, got down around 1.5 and my buddy bumped something back there by the antenna and I was still keying the mic, shot the needle up past max and wouldn't adjust any more. Won't even register on the meter now. No cal, no swr, nothing. My radio still transmits but only for a block or two. I've ordered a compact Cobra, but I'm real hesitant about adjusting anything until I know what the hell I'm doing. So feel free to educate me when you get time.
First off, do not transmit until the problem has been fixed. You'll fry the finals in the radio, or any other radio that you hook up.
If you have an ohm meter, check your continuity between the inner conductor (center post) and outer conductor (ground), it should read infinity or open. This is done on the PL-259 plug on the rdio end of the coax.
I suspect you have a dead short somewhere.
I would totally disassemble the antenna from the mount, the mount from the body, check everything carefully, and start over.
BTW, if your buddy was back at the antenna while you were checking SWR he was affecting your reading. SWR should be checked it a wide open area with the doors closed and everybody in the vehicle if you have friends with you. Anything close to the antenna will have an effect on it.
Also, with the firestick antennas, if you plan on running the rubber cap in normal operation, SWR must be checked with the cap on. I know it's a PITA, but it has a drastic effect on SWR. I put a touch of WD40 in the cap on mine while adjusting to help get it on and off. After I was done, I cleaned out the cap with soap and also cleaned the antenna mast so it would stay on.
If you have a hard top, you should check SWR after taking it off. Same with the soft top. Adjust accordingly and your radio will thank you
