just got my rg-213u in the mail (from copper of course!) and i had copper put the pl-259's on both ends. when i inspected them, i noticed that the holes you solder the braid through were not soldered, and i couldnt see any braid through the holes, just the plastic dielectric. could someone put my mind at ease and tell me the reason for this? im not sure if the braid got cut by mistake or if copper just knows a way of installing these connectors that i dont. would anyone who has had copper solder your coax ends on for you take a look at one end for me and tell me if you see the dielectric, solder, or what? thanks to anyone who will help me with this, as i cant install my antenna until this issue is resolved. matt |

Kid_vicious, my normal procedure for 213 sized cable is to fold the braid back over the jacket of the cable and screw the connector on over the braid.with 1/4" of dielectric exposed you wouldnt see the braid through the solder holes. tech291 CEF#291 kc8zpj |

ALWAYS solder the braid through the 4 holes.....All 4 of them! |

looks like i may have struck a nerve here! J/K i guess there is more than one way to skin a coax. i have soldered through the holes in the past and have had great difficulty getting sufficient heat through the holes. if the connection is merely a physical one (folding the braid back and screwing on the connector), would corrosion be a concern? i guess im just a little dissappointed that i paid for a service to do something that i couldnt do, and they did it just like i would have. if it works well then ive got nothing to complain about. |

No KV,different folks have different ways of skinning a coax.thats just been my method and have never had a failure due to weather or corrosion. |

at cb freqs, folding back the coax and not soldering the holes is not really a problem, although the soldering will make the pl259 more stable. at high band vhf and above, this can cause impedance 'bumps'(the pl259 is not a good 50ohm connector to begin with) and will cause rf to leak in and out at the connectors. |

Speaking of coax, I just put an ohm meter to the shield and the center and I got a dang ol' reading. It was like 359m ohms. I checked the coax with the antenna disconnected and checked both ends I got the same reading both times. Something tells me that I need new coax. Am I right? What would cause this? On the subject of not soldering the shield to the pl 259s I have in the past run coax with out soldering anything, had a flat 1 swr, and could shoot skip real well I ran that way for about two years. The only prob I found was that the pl 259 would work it's way off every sooo often. Yes, I now solder them on. sg569 |

I would say it's just good practice to soldier all connections regardless of the intended frequency used when you're in a final install situation. Do it right or don't do it.-- |

sg569, Sounds like your cabel got some moisture in it. Get some 9913 from Copper and seal the ends well. |

Ok Tech 833, Maybe I'm blind, but I'm not seeing any 9913 coax.I have been through the whole online cat, and I have tried searching the coax out. All I am finding Is coax, no 9913 coax. Have I missed something? That's not like "blinker fluid, Muffler bearings, VW radiator caps" is it??? Thanks,Walter |

Sg569, You are correct Copper does not handle the 9913 coax. Actually the only brand of Coax I use is the Mini 8 and RG8 and RG213, ALL made by Superior Insulated Wire Company which is also the Brand Copper Carries. Superior Insulated Wire Company (SIW) is the Oldest Coax and Wire Company Manufacturer in the US. Lon Tech808 CEF808 N9OSN |

So if a PL-259 is not that good of a 50 ohm connector & has some rf leakage,what would the better connector be?.....thanks, ray |

The PL-259 / SO-239 are very widely used. They are NOT good conector and NOT 50 ohms. Now REALWORLD is we are stuck with them .... Unless you want to change over to TYPE "N" ...... lots of luck. |

Wrk3, Since 1963 I have never found any reason to NOT use PL259 conectors on my coax for my CB/HF Radios, Amps, Antennas, SWR/Watt/Mod Meters, Antenna Switch Controls, Jumpers, Dummy Loads and Test Equipment. Personally to me it is NOT worth the time or trouble or expense to switch to type N connectors as 99% of all CB/Export Mobile and Base radio's use the SO-239 connector to connect the coax to it. And then to do it right you would also need to not only change the Coax end's but the Radio SO-239 connector as well as the connectors on all of your Coax, Jumpers, Antennas, Meters, Antenna Switches, and everything else or it would just be a costly waste of time and money to just change only the one on one end of the coax. Just my personal thoughts, Lon Tech808 CEF808 N9OSN |

LON CORRECT ! and my point the loss is SO SMALL that to do this makes no real sence. YES the PL-259 / SO-239 is not a good connector but is SO WIDELY USED it is accepted as a standard even with all its bad points. Now if you were on 440 mhz or 1296 you would see a change. And ever wondered why so many ham radios use a BNC? because it's the connector of choice for RG-58 / RG-8mini.... and YES they make a type N but the BNC is a bunch cheaper and just as good. |

Bruce, your right, a bunch of the old hams want use anything but BNC or N connectors. I believe some of the old ham amps came with BNC connectors, and maybe some of the old radios, i'm thinking some of the Heathkit stuff did. I've got a bunch of BNC and N connectors that came from a sale, but if I had to put them on everything, I think I would quit radioing.
