Re: Best type of coax to use ... in ... AMSAT-BB Digest,Vol 3, Issue 326




  Make sure you get the correct N connector.  You may have to trim some 
strands out of the center conductor if you get the wrong connector.  I 
had the problem with a local Ham store that had connectors for RG8/RG11. 
Amphenol makes one for 9913 specifically.
