I will add this to the topic of "amplifiers in the nation": to receive DVB-T you need a signal 10 times weaker, if you give the receiver input over 2 mV, expect trouble. And in fact, for the analog at this level, good reception started.
Chrzelice is not equipped with a MUX8 transmitter - and I don't think they will - but note that from Góra Św. Anna, it is broadcast on channel 6, which is the same as from Koszty, Ślęza, Śnieżne Kotłów, Czarna Góra, Sucha Góra and Solina. Differences in polarization are definitely not enough, especially in Lower Silesia. Personally, I think this network configuration is wrong.
Many of my friends living in Lower Silesia signal to me that they have a lot of trouble with MUX8, for example in Brzeg or Prudnik. The northern part of the Opolskie Voivodeship has a very good reception from Kobyla Góra near Ostrzeszów, this signal is stable even in Opole.
And the lack of information about the location (it does not have to be an exact address, a town or a nearby intersection in a larger town is enough) as a "delicate attention" of the moderator.
Do not take the information on the dvb-t map pages for granted, this data is only indicative and should rather be considered as a "wish list". Anyway, like all computer simulations.
And do not give us a list of broadcasting facilities, many in this forum know these facilities from the foundations to the ends of the masts, some even sat on their tops.
PS. I don't see much point in a combo antenna.
