What is this?

[Ruzzell]

Does anyone know what these things are? We keep digging these old things up in our yard. They appear to be a hard plastic with some kind of electronics inside them. Thanks.

I know some radio hams love burying supplemental earthing , expecting in a star formation ... but insulated !
Was there ever a radio station near by (free energy project !)
(still need clues to how much copper / reistance to rule out some weird heater ! )

looks like telephone cable ...

How to tell if it's telephone cable - That stuff is amazingly springy ,resists bending straight a bit like spring steel ? (in UK at least)
{May explain curly ness , unless it was wound up for shot}

I vaguely remember the many years ago they used to make LED net lights and fairy light strings similar to that where the enclosed the LED's and their associated components in little heat sealed plastic sleeves to try to give them some form of IP rating.

Cut one open and post a few pictures of the components inside please.

Have you found out what it is?

He's gone a bit quiet. Maybe it blew up?

I'm hoping things have gone quiet ,due to a "downed" telephone cable !
( snagged a few in town helping a bus get thru in the snow -another cold winter )
( he had unwanted rear end steer on a slight slope/camber )

Ha! Not yet. Thanks, all. I will take my chances and try cutting it open. Will send pics.

That's just the crap copper clad steel rubbish that most of the wholesalers seem to stock now. Proper telephone cable is solid copper. That steel stuff is really awful, shouldn't be allowed to be sold.

Oh well.

Was hoping for some exotic brass/bronze .

Ruzzell - Do you have an update or any more pictures on these as yet unknown terminations? I cannot hold my breath much longer.

Thanks, all, for your input. I'm attaching a couple more photos. Several of these were buried just under the surface of the ground next to my garage. We live in suburban Philadelphia, so I don't think I have to worry about them being some of kind of leftover war ordinance or something. But I am a little hesitant to try to cut them open, in case they are a type of detonator or so. I'm intrigued and surprised that they aren't instantly recognizable to the electricians in this forum.

Ruzzel iv got to agree with the group it’s similar like a fiber optic splice filled with silicon or some kind of telephone splice. I’m like Dan cut it open and see if it goes bang

Thanks, all, for your interest and patience in getting my reply. Well, I finally cut the thing open with gloves on and hiding behind a box, and I'm happy to report that there were not explosions. Here are the pics. I will also say that these gadgets kept digging up under a huge 120-year-old English hew tree that a bunch of boys used to play in and around in the 1970s, with tree fort etc. I don't know if these might have been part of an electronics kit? Maybe a buzzer system or something? Appreciate your input on this modest little mastery.

I am sticking with this being a transducer to emit sounds into the ground (around the old tree) to repel vermin (and thus protect the tree).

They look like, although hard to tell bi-metallic switches.
