[TowerTalk] Life expectancy of RG-213

[TexasRF at aol.com]

Tom and all, very few 8X cables are made with non-contaminating jackets. I  
don't have a Belden reference here but I would be surprised if their's is  
non-contaminating.
 
Quite a few years ago, I had 8X specially made with a non-contaminating  
jacket for sale at Texas Towers. We still offer  this product if anyone is  
interested in a long life small 50 ohm coax. Any coax, or rotor cable for that 
 matter, branded Texcom Wire and Cable, has a non-contaminating PVC jacket.

Hi  Don

What makes coax turn black anyway??

I was checking some  feedlines here and some off-brand RG8X I have and the 
center conductor and  the sheild turned both black.  It was not just at the 
ends but a long  way back from the end.

It doesn't look like it was wet.

Looks  like I'll have to get rid of a bunch of it.  73

Pete,

Beg, borrow, buy a TDR and look at it that  way.

Most coax will last many more years than people  believe.

Problems occur from moisture ingress, but, if trimmed when  necessary,
will do just fine.

My rule of thumb is:  If the  shield is shiny, it's OK.

I have 100's of feet of it ready to put into  use this Fall/Winter season.
Now all I need to do is get the  towers/antennas up!

Good  luck
