I just spend the whole day , replacing my sat-cable , going from my dish (diseq) to the receiver.
I have my dish hanging on the garage (W...'s order) , as it wasn't allowed to hang it on the house
This means i have around 30m (120dB) quad-screened cable , 15m "dug down outside" from the garage to the house , and 15m in the 90cm "crawl cellar" to the receiver.
When i installed it it was working excellent , lot's of signal (120 cm Alu Dish - 4 heads) , 120dB cable and SPAUN diseq.
Last year (May) we lost the signal , and was suspecting a large tree nearby. But the signal didn't come in the autumn , where the leaves fall off.
I had the cable running in some "cheap flex tube" on the outside path , and was then expecting that this flex-tube was somehow breached , and that the cable had been under water for a long time. The cable crosses a place that is under water during heavy rain.
Today i replaced the cable , and was quite astonished when i discovered that the error was inside the "crawl cellar".
When i withdrew the cable fully ,i discovered there was a spot that was "rust colored" , and felt wrong. The strange part was that the cable "outer protection" plastic was intact , just discoloured on the "rusty" spot.
I did cut the cable around the rusty spot , and opened it up.
There was absolutely no screen left , just "white powder" ....
I don't know what happened , but have a suspicion that the cable ... Lying in the sandy ground in the "crawl cellar" might have been on some metal at that spot and that some kind of "electrolysis" or whatever has happened there.
It takes a full day to replace , due to digging it down in the lawn 4 meters , taking up the concrete tiles from the tereasse for 8 meters , digging it down there. Refit the concrete tiles and curse when they doesn't allign nicely. And then there is the 15 meters in the "crawl cellar" ...
So this time i decided to lay the "outside" 15m cable inside a garden water hose (for protection) , and then run the last 15m in the crawl cellar in flextube. So the cable doesn't come in contact with the "ground" at any place.
I have just finished , and we can now see sat-tv again
But what did happen with the 15cm cable where the screen became "white powder"
Even through the outer plastic-protection
