Hello, again, everyone.

Last week, when I had some help over here to resurrect my 40-foot mast to 
support my HF antennas, we decided to put up an extra VHF/UHF J-pole antenna 
on the very top of the mast.  This was kind of an impulsive decision, so I 
had to scrounge together what coax I could for the feed line.  In my 
scrounging efforts, I found what I thought was a 50-foot piece of RG9913 
coax.  It only had a PL259 on one end, but I wasn't too worried about the 
prospect of putting another connector on the shack end at some point.

Today, out of basic curiosity, I thought I should check to see exactly what 
kind of coax I was dealing with, and was somewhat dismayed to find that, in 
reality, it is RG213U.

What I need to know now is whether I'm in serious trouble here.

I know that RG213U is not as high-quality as RG9913, but I'm hoping it will 
be reasonably adequate for an outdoor back-up VHF/UHF antenna.

If this kind of coax is not suitable for what I need, I may have to bribe my 
friend to climb up there and replace it with something better.

I'm going to a local swap next week-end, so can pick up some 9913 there if 
this looks to be a truly necessary step.

I'd be interested in any thoughts.

Thanks, and 73 from Tom Behler:  KB8TYJ
