Flexible Coax

Does anyone know of a brand of RG-6 Coax that is highly flexible? The one I've got now gets very stiff below about 50 deg F. It gets very upset with me if I try to uncoil it. I tried uncoiling it and laying it out in the sun, but as soon as it cooled down, I had a 25ft stick!
Thanks, Dick
  • You could try using RG-59 coax. It's thinner than RG-6 and would be easier to manage. The down-side is there's more signal loss. A friend of mine is using 100 feet for his Dish satellite.

    If you are dead set on RG-6, you could check a brand called Canare. They make some very flexible cable. I don't know if they make a direct replacement for RG-6. If they do, I don't know if standard F connectors would work.

    What can I say Hobo.. Folks with ID's like Mine (WA8YXM) Tend to be CUSTOMERS of that story (And as a matter of fact I am)

    I also shop All Electronics, MFJ (They made my wrist watch,,Which I never have to set), GIGA-Parts, DX-Engineering,, Amateur Electronis Supply and more.

    Now if you would like to make that store name easier to remember...

    go to http://www.arrl.org

    Find a club near you

    Take a license course and exam

    And go shopping.
  • Thanks for the info folks, I guess that my MH just came with the cheap cable.

    Special thanks to wa8yxm (John). I have been beating my head looking for the name of that store. Thanks for the help.

  • If you "roll" it up on a reel instead of coiling it you will have better luck.

    If it is real cold attach one end to a fixed object when unrolling and keep the cable tight.
  • There are 3 different dielectrics used in coax:
    - Solid poly(whatever) stuff
    - Foam
    - Air

    Solid core is not very tolerant of cold tempetures and just stiffens up. Even in California when I want to straighten it out I have to lay it out and let the sun warm it

    I'm not sure where you find 75 0hm foam cable anymore, but look for something called "Superflex". It did exist in 75 ohm, and is still available in 50 ohm.

    Air coax is for much larger coax and very stiff

    There are many types of coax.. Standard RG-6 should NEVER be coliled around a core less than six inches in diamater.. This is your first mistake.

    They make some very small coax.. Very very very flexible.. But also very high loss.

    Here is a thought... Your profile says DENVER, CO

    Also in Denver, CO, is a store called Ham Radio Outlet

    Large (VERY VERY LARGE) selection of coax and a good selection of folks who know more about it than I do (And that is saying a lot).

    These folks live, and breath, Radio.. and COAX is .. Part of Radio.
  • I have used many brands of Coax and Ethernet cable in my job and I have hated Canadian winter the most when we have cabling jobs to do. It does not seem to matter what brand of cable I use, it all get rigid below freezing and takes about 15 minutes warming up to be pliable enough to actually use. It is just a fact my techs and I have had to get used to in our job. The problem is quality of cable varies and if you do find one that does not get stiff in the cold, I would be very suspicious of the quality of it as I have never found one that does not stiffen, and the use of quality plastics for shielding are absolutely critical to the performance of the cable. I would also never try to uncoil Coax in very cold temps (around 0 degrees F). I have actually seen Coax fracture inside (where you cannot see it unless you strip it down and look for the fracture)
