paying the extra 15p/M for quality cable like CT100 or WF100 will improve things, i never use RG6
So called RG6xx and so called CT100 can be:
* all copper decent braid
* All copper but braid too light is a problem when foil cracks
* core steel or aluminum with copper plating
* alumium foil & copper Braid (bad electrochemical corrosion)
* aluminium foil & tinned copper braid (bad electrochemical corrosion)
* plastic foil with metalisation and aluminum briad (yuch).
* Air core (best but easily damaged by kink)
* Old type foam (absorbs water badly and attenuates terribly)
* New type foam (no water absorption)
Variatons of
* Soft PVC outer (cracks in UV outdoor and porus to moisture)
* uPVC
* Trunk quality plastic, very stiff and mechanically strong, UV and water proof.
Unfortunately a lot of electrical wholesale have only 3 kinds of cable.
1) Skinny coax like RG59, except alumium and may or may not have foil. Like Chorus indoor cable in appearance.
2) So called low loss coax (maybe a choice of colours). very little braid and no foil. Virtually no screening effect.
3) Cable that might even be labelled RG6 or CT100, but more often simply has satellite printed on the drum. Copper plated steel or aluminum core, poor aluminum braid and plastic metalised foil.
The quad shielded RG6 from belden I have used in the past is as good as they come
If you want a real difference look at RG58 versus RG223 yes I know its 50 ohm.
I rest my point funny thing is I just let my master cabler licence lapse
