Can't hear when too close

Are you going to replace the whole coax instead?

2" is bad from corrosion 2" is going to get trimmed, that's just practical. The coax itself isn't going to last long enough to worry about it in the "long term".

 

Only way i would reuse would be its all i had..If its been there long enough to be exposed and corroded,its gonna be degraded all over...
You almost sound like a buddy of mine...Scared to spend the $ on fresh stuff and try to save a buck when its not helping the radio at all..

Your gear,your decision..

 

That's not a known cb shop to be doing any antenna work if it's the one I'm thinking of..

 

You just buy new coax and be done with it theirs actually fairly good coax with really good pl 259 connecters in alot of them . And it's about $20

 

There's a lot of good techs---- good cb shops who don't even set swrs their too busy with repairs.. some of the shops have guys come in usually in the afternoons to do antenna work.

 

Whoa wait what ?????? Your kidding right !!!

 

Trimming coax ok well that's a totally new one on me.... wtf

 

OMG guys, if he is trimming the coax back, that means the connector wasn't sealed right and there was water getting into it so trimming it back cleaned up the connection. This happens a lot on some installs and one reason why I recommend N connectors over UHF connectors.

 

The way that's worded has/had me confused ???

 

Confused about what?

OK let's break down the issue.

With some coax connectors, even crimp on, they don't seal well. Many don't use any sort of tape sealant so water and sometimes other things like salt (like when there is salt used on the road for ice) get into the connection and travel down under the outer protective layer of coax - this happens on all commonly sold coaxes, some specialty stuff has Teflon/adhesive sealer that is heat activated and won't have this issue.

BUT a lot of times the coax connector will actually have some moisture in between the center conductor and the outer conductor which effects the performance of the feed-line at that point. Some consider corrosion as one of the indicators of this, others see corrosion as the cause but really it is moisture that is effecting the performance.

SO in his case, he did the same thing I've done many times when this was an issue, trimmed the coax back a few inches and put the connector back on.

I have a random wire dipole setup with an open connection to the coax, using the actual coax as a BALUN and I had it sealed with some pretty good RTV adhesive. I had to take it down and cut four inches off the coax because the seal failed and four inches up to the end has moisture in it under the outer protective layer.

Now one thing I have used without any issues with moister are N connectors, I have them on the radio, I have them on the antennas and the tuners. These connectors actually seal the connection at both the coax entry point and the actual connection to the other connector. I don't see why a UHF connector would be used when there are alternatives that are much much better.
