Skywire coax cable vs. regular coax cable
Is there a difference between a "Skywire" coax cable and a regular
coax cable you get from Radio Shack in terms of quality or compatibilities? |

I think Grove Enterprises (reseller of equipment and publisher of Monitoring Times) might have trademark to an HF antenna called "Grove Skywire". It is an insulated coax-type antenna that functions as a long wire or random wire, depending on how much of it you put up. Radio Shack's RG-58U is a heavy duty and reliable coax that provides many years of low-loss service. I eventually replaced all of mine with more expensive Belden equivalents but doubt there is much difference in velocity or shielding, etc. Jack Painter Virginia Beach VA |

Jack - When buying coax -- be a "doubting Thomas" - there is a large amount of "junk coax" on the market. In fact many CATV companies are now replacing poor quality homeowner installed coax -- in order to handled new digital channels, Internet and phone services (up to 2 GHz). When I buy Belden (or Times) I know what I am getting, its quality and consistency. I also purchase some coax versions by Press, TheWireman. http://thewireman.com/index.shtml I have known Press a number of years, and will ask him to look at the shielding, braid and jacket formulations. The especially like his marine RG-8X which meets unique marine and water/wet installations. As for RadioShack, I do not use them for coax purchases. They are becoming a cell phone retailer (and battery operated toys for Christmas) in many parts of the country. Allied Radio is no longer part of RadioShack - and it shows. While some franchise owners and stores work to meet local needs, I do not find this on a nationwide basis. GB |
For outdoor, flexible coax I have found that Bury-Flex (TM) from Davis is
ideal. This link takes you to the part of his site where quality coax may be found: http://www.davisrf.com/ham1/coax.htm It is daft not to use good coax. As others have observed, No-Brand and RS should be avoided. 73 Mac N8TT -- J. Mc Laughlin; Michigan U.S.A. Home: |

One thing I didn't see mentioned in the other posts is the quality of the wire used to make the coax. I have seen this problem with both Radio Shack Coax and their hook up wire. I beleive it is all made in Japan and they use a different copper alloy (or possibly tempering) than the US companies. This makes the wire more brittle and it tends to be stiffer. Read this as: You have to be Very careful not to nick the wire or it will break when it flexes. The US made copper wire I have used does not have this problem. Jim N8EE |
