Special type of coax - need info
Locked
 
|
30 years ago, when I was living in Fairfax County, VA, the TV cable was
shipped around on a double coax cable. It resembled lamp cord or zip cord, and was two parallel coax lines with a webbing between them. I am in need of the proper name for that cable, so I can search some out. I used it as feed for a full size lazy 80 meter loop - about the same as tuned feeders would be used. It worked very well on all bands - providing lots of DX and a ton of local coverage also. Not a tri-bander - but it beat the socks off other wires and verticals. I want to duplicate that antenna this spring. Thanks, Bill W2BLC K-Line ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

I've seen the name "TwinAx" somewhere. It was probably networking or
terminals, at least 30 years ago. 73 -- Lynn On 1/16/2018 11:55 AM, Bill wrote: > 30 years ago, when I was living in Fairfax County, VA, the TV cable was > shipped around on a double coax cable. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Twinax under that name was a two conductor shielded coax like cable for balanced antennas. The R-389 for instance had a connector for that kind of cable.

That was two pair for IBM networks of about 25 years ago. Stiff and ugly to work with. David K0LUM > On Jan 16, 2018, at 2:26 PM, Lynn W.

I am NOT looking for TwinAX nor two coaxes wither their jackets bonded. RG400 is what I'm looking for, and thanks to those who correctly read my mind. :) 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

That is a coax with a double shield except the shields are each insulated.

Thanks to all that replied. I was reminded that the shielding is
aluminum etc. I had forgotten that little detail over the years. I do now recall that the cable I used did have copper - it was used exclusively at the head-ends and was hard to get. Hence, I think I will parallel some RG8X, use cable ties and Goop, and make my own. That way I can make solid soldered connections for everything. Gotta do things right the first time and have it last many years with no further service. Thanks for the reminder.
