Distribute telephone cable at several locations on the property

Hello,

for example, I need to lay a telephone cable A-2Y(L)2Y 2x2x0.8mm² to my cistern for level measurement, but also at other places, like the garden gate. I want to collect the cables in the garage and bring them into the house with an A-2Y(L)2Y 10x2x0.8mm² cable.

The distance from the garage to the cistern is about 25 m. Theoretically, I could use a 4x2x0.8mm² cable to the cistern and from there further to the garden gate, which is another 25 m away. However, I wonder how or where I can do the wiring? Are there underground or above-ground waterproof junction boxes?

yes, there is (just google Cellpack). You have to take a "large" one, then equip the interior with an LSA distributor (standard LSA fits exactly up to max. 0.8mm²) I’m not questioning the purpose now, but I recommend using better earthable CAT7 cable.

Hello, I am laying a CAT7 cable in parallel for the hands-free system. I want to use the telephone cable at the cistern to connect a level sensor and at the garden gate for one or two reed switch(es).

I have now done further research and will probably make a distribution box at the top of the dome in the cistern.

Are there underground or above-ground waterproof junction boxes?

Friedl junction boxes. They are IP 68 and relatively inexpensive.

possibly additionally a coaxial cable to the cistern, then you can also switch to ultrasound if your currently planned measurement doesn’t work. ;)

Friedl can sleeves. They are IP 68 and relatively inexpensive.

I also have some in use. Unfortunately, I cut the opening of the rubber end cap too large on one of them. Is there a tip on how I can fix this without having to buy a new sleeve right away (I haven't found any replacement parts anywhere)?
