    Yep.

    I use them ... both the RCA and F-Connector versions.

    They are fairly easy to install (sometimes the little

    red rubber seal inside connector requires a bit of

    brute strength to screw the housing together at final

    assembly).

    They produce a very solid and reliable "no solder" termination. I tried to undo a termination on one cable

    and ended up cutting the end off because it was so

    difficult to "undo".

    As far as digital use, I cannot comment because I only

    use commercial cables for my digital needs. I would

    check to see if they are compatible with 75Ohm applications.

    Smarthome.com usually has them on sale.

    Radioshack has them on sale too. $4 and $3 for shipping

    I've just sent e-mail to centerpin.com asking if their connectors are 75ohm compatible...

    update

    centerpin.com said nothing so far.

    So I just installed a couple. You have to be x-man with steel finger-tips to put them on, but when you done they sit dead tight.

    How do you check if they 75Ohm compatible?

    No fingers needed. Just a couple pair of needle nose

    vise-grip pliers.

    As far as testing for 75 Ohm compatibility, you need a

    signal source and something to read it. The only thing

    I know that will do it is a HP test set which is super

    expensive and not worth renting because renting is still

    cost prohibitive and it would be a while learning how to

    use the thing.

    I believe the commercial guys use known materials/formulas

    that yield a 75 Ohm cable and then send a representative

    sample to their labs or off somewhere for the final nod.

    Maybe someone else has some input.

    I think the cable will work fine and there is only one way

    to find out.

    Yeah, if you have some tools it's easier, but what I meant to say that you can install plugs right on the home depot parking lot. [​IMG]
    What is HP set? I have bunch of tone generators and whole variety of meters here in the hardware lab. But I have to know what to do. :b

    As far as a true 75 ohm RCA, there aren't any. This has to do with geometrical considerations that preclude the construction of a 75 ohm RCA. It's possible with some fudging to get close, but not 75 ohms. Now before you Canare guys start hollering about their RCA, I'll tell you I contacted them some time ago and their reply regarding their RCA is that it is they run a sweep test with a 75 ohm cable attached and use as a criteria that the VSWR

    HP = Hewlett Packard.
