    The above was a reply to the last time you made this comment. Perhaps you'll read it this time.

    The question is about what to do now not what might've been done differently in the past. Digging a 20m trench seems unlikely to be a better solution at this point in time.

    want to buy a magic wand??
    it'll fix everything, honest.

    I was thinking a PtP kit. I never realised getting WiFi 20m LOS needed magic

    Like most of us I have a box full of old routers and wireless modems and access points which I would love to see in use.
    I don't know about PtP. Regarding old routers, yes they can be re-purposed as wireless access points, but they cannot be made into wireless bridges (ie. a wireless link connecting two wired networks).

    Just to add that the above weatherproof cable was run underground.

    It's a bit far for WiFi repeaters so I wondered if there's any chance homeplug might travel outside our domestic wiring?

    Otherwise we'll either get mobile internet or see if we can wing a cat 6 cable down there. We'd likely want internet for security cameras so I'm a bit dubious about 4g... Not for the quality but the data/cost.

    For reference.

    This 'ere mains supply, how many overhead wires are there?

    One or two?

    (Obviously there's two, but are they in the same overall insulation or two separate wires?)

    Do these wires or wire come from Your Very Own stepdown transformer on a pole?

    In other words, exactly how rural is this?

    Is this relevant or are you scoping out my joint

    We've got a string of old-fashioned wooden poles up our lane from the road which service our property alone. It's a single cable - insulated and pretty chunky though as you say I'm sure it's two fat single-core cables intertwined. There's no box where it reaches the house so I think it must be 240V with a transformer a few hundred metres away.

    Just wondered really.

    Chap up the road a bit has a transformer on a pole fed from the 3 phase 3kV3 lines that go all the way to the top of the hill for the farms.

    The feed over the road to his house is a single cable, "live" and "neutral" with I suppose "neutral" being defined as the wire that's grounded at the pole mounted transformer (I dunno really, but I assume that's how it works).

    I was wondering how the alternative of two widely spaced lines would transmit the rf from a powerline interface thingie since the impedance of such a line is wildly different from the twin & earth found buried in the walls of a house.

    The fat enclosed twin cable is probably fairly similar to twin and earth from the impedance perspective.

    Your installation is TT so presumably there's an earth electrode at your house & an earth electrode at the cabin.

    Which might lead to a difference in the earth potential between the two.

    I'd be a bit twitchy about connecting between the two with CAT6 in case of circulating currents in the screen.

    Like a giant hum loop.

    Not to mention what happens with a near by lightning strike.

    Indeed, we have earth rods at each location. Potential difference is one reason I shied away from a cabled approach though I didn't really know what the actual problem was
