NEWBIE QUESTION!

#21377

Post by BMAN212 »

Searched around and I'm either dumb or blind or both. I have a buddy with a new out of the box radio showing continuity from the center pin to the outside shield at the antenna jack. Mind you this is on the back of the radio. Correct me if I'm wrong here but does this not indicate a problem with the radio internals?

Hmmm,
Don't know.

I take it that it failed to work, thus the meter test?

If it has a warranty, and warranty stickers, don't break their seal!


Edited in later....
If I edit in, what Phaze said later, will it look like I had the better solution first?
See below for a better answer....

Go get em' Phaze.

If you dont have a problem and was just checkin for the fun of it, measuring it with an ohm meter will show a complete circuit but with a measured resistance because you have to go through the circuits to get to ground.

Actually he IS having a problem, which is why he checked it. When he said that there was Continuity at that point it struck me as odd but again I'm a newbie and wasn't 100% sure. Let me go nab his postfrom our other forum and paste it here for you all to help me trouble shoot for him... IF that's alright with you.

EDIT***

HIS FIRST POST

Just moved my antenna to my ARB front bumper. I'm having trouble with mega high (pegged) SWR on all channels and am thinking it's got to be the ground. I dremeled off some the of the powder coat underneath the stud nut and also under one of the bolts to the frame to make sure I was getting good contact. It was previously on the oem roof rack with an aluminum mirror mount and worked excellent with low SWR (1.25) Moving the adjustable antenna tip of course doesn't do any good as the SWR is high across all channels. I realize that the front bumper isn't the optimum mounting point and the roof was likely more ideal but there's no way it's gotta be this bad.

Any suggestions?

AND A LATER POST

Meter says the mount is grounded well. No short within the mount itself. The coax isn't shorted. The SWR meter isn't shorted at either coax input. The CB shows continuity at the coax input between the center hole and outside threads

I would put that radio in another vehicle with a known good coax and antenna for a test.

What is being used to test continuity ?

If an ohms meter, how many ohms are reading and on what scale.

Has the ohms been tested on the cable and on the antenna mount.

Try to check the ohms readings at the antenna ground ( threads ) to its mount point.
