The main qeustion is not about what type of coax to use but the length of the transmission line between the duplexers and the repeater. Yes I am about a 3 weeks into the group new. Thanks Will Russ Stafford wrote: >A few things. >RG-213 is single shield RG-8 coax so that would not be good. >

A few things. RG-213 is single shield RG-8 coax so that would not be good. Keep in mind that Times is selling coax. It is not as much the shielding but the fact that the shield and the foil move and cause noise in your system. It has been talked about time and time again here on RP. Good luck,

Well, I don't like 9913 because it's too easy for the center conductor to move and change the impedance of the cable. I had some 9913 on a UHF repeater back in the 80s, and it wasn't as good as the RG-8X that replaced it. Yes, I know 8X isn't exactly repeater quality. At the time I was in my teens

Maybe you are new to the list.  This topic has been discussed in detail (even just recently) and it has been shown time after time that the dissimilar metals (tined copper braid, over an aluminum foil) will eventually cause noise in a duplex environment. Relatively new yes, but then new people

Don't use 9913 in any repeater setting. Either find some RG142 or use hardline of some sort. LMR400 is not even a good choice. This I can affirm to very quickly. The shortest route is what I took for my jumpers. Mathew -Original Message- From: n2odw [mailto:[EMAIL PROTECTED] Sent:
