Short Circuit on Antenna Cable: Storms & Electrical Devices Impact, Decoder Reset, Triax TMS 9X6P

The problem is:

Once in a while, most often during a storm or after connecting some additional electrical devices, such as a drill, to the network, there is some kind of short circuit on the antenna cable.

The effect is that the decoder gives the message about the lack of antenna signal, then I have to either reset the decoder (longer method), or remove and insert the antenna cable (now in the summer I have not tightened the plug, so that it would be faster, because every now and then a storm ). It looks like a short circuit would occur with minimal voltage invisible to the eye.

The antenna sockets are next to the contacts, the signal is separated by the Triax TMS 9X6P, the cables are released in the walls. In total, 3 separate TVs and set-top boxes are connected. The problem occurs one at a time, when one of the decoders gives a message about the lack of a signal, the others work correctly.

Is there any way to get rid of the problem?

These three TVs operate from one antenna or separate?

The antenna is one, the signal separates this Triax switch from it.

Maybe you have a distorted (too strong) signal from Multiswitch?
You won't know it without the meter.
What sockets do you have - terminal or so-called through?
Is this happening when watching SAT or terrestrial or both?

The sockets are final, I only use TV SAT.

Start by switching decoders.

And the electrical installation, is it certainly OK?

That I interrupt timidly how do you know it's a short circuit. After all, there is no signal on the decoder (if I read correctly), and as far as I know there is a short circuit message when shorted. In addition, I can not really imagine a short circuit that occurs during a storm or turning on the drill.

Well, no signal and a short circuit - these are probably two different messages?

I don't know much, I thought it was a short circuit because you need to reset the decoder or remove and reinsert the antenna cable. With normal signal loss, this one just comes back after a few seconds. All other decoder functions work at all times.

My wife regularly works with a grinder and this is the rule, a fired grinder is an error message on one of the decoders. And as for the storm is a fact, there are also signal fades, but such as I wrote above they return after a few seconds, in the latter case only the above helps.

Perhaps it is the fault of the electrical installation, unfortunately the summoned electrician did nothing. Certainly this is not the fault of set-top boxes, I have already processed several from ordinary DVBTs, through polsat to nc +. The problem occurred at all.

It is normal - storm clouds obscure the signal but it is a temporary phenomenon - so let's not mix the storm in it. Remains of interference in the network (sparking)
A few questions...

Is the problem also on DVBT?

Does it occur in a specific outlet or in the whole house?

So you can argue that the culprit is Multiswitch.
The easiest way would be to change it.

That's what I was heading for. But if the problem is only in one socket, you can simply unplug them to another output. And since there are three TVs, one is definitely for use. But so far the author has not answered my question.

Well, but if turning on the grinder causes perturbation, it is something with the grinder and / or the installation of the el.- the device should have an interference filter - or there is something in the electrical circuit in the distribution of the sockets

As far as I know simple power tools, rather filters do not have them, while power supplies for electronic devices (multiswitch tuner)

- unscrew any of the cables that comes to the multiswitch from the converter, e.g. from Hot Bird

A good idea and if it will be a Hotbird and the cable will be HL (Horizontal Low or 18V 22kHz Off), it does not have to look for the effect, just turn on TVP1HD. The second alternative is VL (Vertical Low or 13V 22kHz Off) and TVN HD is in this range. Generally, most Polish stations are in these two ranges.
