Receives Only MUX8 - 0558 Directional Antenna: Low Signal Strength & Roof Adjustment Issues

Hello,
for some time I have only received new tv, wp ... that is only channels from MUX8. Signal strength is 30% and quality 80-100%. I moved the antenna on the roof quite precisely but it did nothing.

Has anyone had a similar problem and solved it ??

Greetings flu

Probably something happened to the antenna for MUX 1-3. What antenna is it and from what direction does it receive? With or without an amplifier?

Directional antenna for digital terrestrial DVB-T Cabletech model ANT0558:

Antenna in RTCN Krynice and mine in Łapy. Thank you.

The antenna you replaced is an antenna for the UHF band, i.e. channels 21 to 69. MUX8 is transmitted in the VHF band and a completely different antenna is recommended for such reception. If, despite this, you have MUX8 reception from the VHF band (8my channel) from the current installation and you do not have UHF reception - channels 22, 46 and 49 from Krynice, then I would check the antenna cable and plug at the receiver first. All you need is a torn braid in the cable to have what you currently have.

Check all connectors carefully. You don't write anything about the age of the cable, but if the outer insulation is cracked somewhere and water has got in, then the cable rots inside almost instantly.
