[TowerTalk] Type N and PL-259 Connectors for Belden 9913 Flex

[Mark Spencer]

With regards to "9913 flex" (ie Belden 9913 F7 ?)  you can easily attach standard PL 259 plugs by cutting off one of the strands of the portion of the center conductor that is soldered to the center pin of a PL 259.  Although I wouldn't reccommend this practice, it's arguable how much extra loss and or miss match this would cause over and above using a PL 259 at VHF or UHF.    At high power levels where you would be concerned about the current carrying capacity of the conductors this is probably not a good practice. 
   
  If you are going to use N connectors I would go out of my way to get the correct connectors with the special center pin that will accomodate the larger center conductor.   My recollection is that these were quite finnicky to install the first few times, so if you have not done this before I would buy a few extras and allow yourself some extra slack in your cable runs in case you need to cut off the cable and start again.
   
  Good luck.

  The 9913 flex, LMR400, buryflex (and maybe others I don't know about) 
have a larger center conductor that will not fit many of the 
"standard" connectors. N connectors for sure you need special 
connectors. I have used some "standard" solder type connectors with 
9913 flex, but the crimp needs to be special.

Experience is the thing you have left when everything else is gone.
