Switching large electric power without proper decoupling create spikes which have high energy and very high bandwidth. This can be compared at some point to EMP.
I have meant rather along the power lines noise.
E.g. using digital video output from videocard, to monitor picture is fine. But during temporal period I used integrated intel graphics with analog output. At that time monitor picture was very eye-disturbing, if my microwave oven was working.

My advice - instead of building common antenna installation, use home antenna, passive, no amplifier.
I am afraid my low floor location ad position away from signal,
without direct visibility and with reflection from other buildings will not be satisfactory.

I used initially a simple dipole, coming with my receiver,
but strength and quality was very poor. Than I bought room active antenna,
strength and quality better, but still not excellent.
The common source was much better.

All that struggles are not worthy for me to solve.
Either I can take the signal as it is,
either I fix it and I already know how.

Thanks all for the support.
