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. 73, Jim

I use them all the time, and have not had to use "trimming dimensions". It is very easy to see where to trim with these two piece connectors, just put the cable end near the connector and it's pretty obvious where to cut things (much like a PL-259). I have found them to be very acceptable N connectors and have done dozens of them without a trimming chart.

Someone mentioned the 2-piece type N connector for 9913 type coax. Does anyone have the trimming dimensions for those? I had to make up my own and wonder how good they are. 73, Harvey K5HV

Installing a classic clamp type N connector like the Amphenol 82-202 (UG-21D/U) on flexible coax with a real copper center conductor (RG-8,RG-213) is both easier and has a much higher probability of success than installing the common PL-259. You only have to make one easily accessible solder connection.
Take a look at http://www.amphenolrf.com/products/assemblyInstructions/280.pdf http://www.amphenolrf.com/products/assemblyInstructions/280.pdf http://www.amphenolrf.com/products/assemblyInstructions/280.pdf to see what is involved in attaching classic clamp style N connector.

After problems I had on Field Day in trying to operate the satellites, I am looking to upgrade the coax I use between the preamps and the antennas. I am using 9913FX from the IC-910H and the preamps. I had been using RG Mini 8/U for the connection between the preamps and antennas. Should I also use 9913FX between the preamps and the antennas? The run between the radio and the preamp is 50 ft. The run from the preamp to the antennas is about 10 - 15 ft depending on where I set the antennas up. I am concerned about how flexible the 9913FX would be in terms of the antennas rotating back and forth. I was planning on ordering the cables pre-made from CableXperts since working with N connectors isnt my strong point and dont want to worry about my soldering and having a good connection on both ends of the cable.
Any suggestions appreciated.
Thanks, Ron KA4KYI

I did a very un-scienfific test with one of these -- I put it on an old chunk of cable and gave it the "spin test".
Swung the cable around rapidly and watched it fly off the end and across the yard.
There's just not much there holding it all together on that type of connector. :-)
