[TowerTalk] L-Com 400 coax

[Roger (K8RI)]

I can't speak for L-com LMR 400 like cable, but Times Wire LMR has a 
very short permissible bend radius for permanent installations of only 
1", or a repeatable bend radius of 4" 
http://www.timesmicrowave.com/wireless/index.shtml which is listed as 
the smallest bend radius for any cable of that type.  I've compared 
CNT-240 to LMR-240 and the CNT appears to be more rigid, but that tells 
you or me nothing about the L-Com cables.

So for stubs wound up into coils they would easily fit into a relatively 
small space depending almost entirely on the overall length.

You can find Times Wire LMR-400 available at prices low enough that 
purchasing knock offs is hardly justifiable. I've been paying about 
$1.29 USD a foot for LMR-600, and have replaced all except the leads 
from the  remote antenna switches with it. Crimp on N connectors are 
about $10-$13 USD.

What the tremendous jumps in aluminum and copper prices are going to do 
to the coax cable market is hard to say, but if you need the stuff I'd 
get it now. Two increases in the market. Two weeks ago 30% and last week 
another 30%. Last time it was mainly copper, this time it's copper AND 
aluminum.
