    It's not just that it's RG6 - it can still vary dramatically in quality from brand to brand, some cheaper coax can be a smaller overall diameter &/or the plastic outer & dielectric can be soft & capable of crushing resulting in a poor fitting or over time.

    Webro WF100 is relatively expensive but it's not only a well respected & approved coax, good quality self seal compression fittings will seal on WF100 to their specification where they may not on cheap coax.

    There's also Triax TX100 as an easy recommendation - they are similar in quality & price- the main difference is the copper in WF100 is near pure copper & tx100 uses higher tensile copper alloy but the additive adds much more strength & only about 6% to the attenuation figure so there are applications where one would look to using the stronger coax where that small added attenuation is a reasonable trade off eg the relatively strong signal wise sky/ virgin & most irs's etc.

    Agreed, for example CCS (copper Coated Steel) is OK for a few connections but that's about all.

    The problem with steel wire is that it has a high resistance. The copper coating reduces this for high frequencies but the steel still has to carry any DC current. So, for applications where it has to carry current to (say) an LNB, you must calculate carefully the voltage drop in the cable because even 1 volt drop could be enough to prevent the LNB from switching to horizontal polarisation.

    Why the insistence on RG6? Are you in America? RG6 alone does not define the cable type. In the UK anything listed as "RG6" is probably best avoided if you need it to carry current.

    Hence people saying WF100.
    RG6 defines (if I remember correctly) the dimensions and impedance only.
