FAQ
TL;DR: 30 kW MUX‑3 power can distort reception; "We still don’t know where the pick‑up point is." If you only see TVP near Wrocław/Ślęża and lack Polsat/TVN, verify location, antenna setup, and run manual scans for missing multiplexes. [Elektroda, irekr, post #21299679]
Why it matters: This FAQ helps viewers around Wrocław/Ślęża quickly restore missing commercial DVB‑T2 channels (Polsat/TVN) by checking the right transmitter, settings, and hardware.
Quick Facts
- In Poland, MUX‑1 and MUX‑2 use DVB‑T2/HEVC, while MUX‑8 remains DVB‑T (VHF). Confirm frequencies and polarisation in the official table. ["Emitel: Strefa Widza — Odbiór RTV"]
- For manual scans, use the Ślęża/Wrocław listing; UHF channels 21–48 use 8 MHz bandwidth. ["DIPOL: Dane nadajników DVB‑T2 w Polsce"]
- Operator maintenance/outages can blank MUX‑1/2 for up to 4 days; check status before replacing gear. [Elektroda, MDD, post #21296702]
- ~20‑year‑old installs often need new coax, power supply, and connectors; overhaul the entire run from antenna to receiver. [Elektroda, _kli_, post #21297863]
- If you already receive TVP1/TVP2 in DVB‑T2, your decoder supports T2; the issue is reception path, not codec. [Elektroda, Jacekser, post #21297816]
Why do I get TVP but not Polsat/TVN from Ślęża?
Because you are receiving MUX‑3/6 but not MUX‑1/2. TVP is on MUX‑3/6; commercial channels are on MUX‑1/2 (DVB‑T2). Verify the decoder scans DVB‑T2, not DVB‑T. Then align the antenna and manually scan the MUX‑1 and MUX‑2 frequencies for your locality. "These are MUXes broadcast in the system DVB‑T2; DVB‑T only MUX‑8 is broadcast." [Elektroda, Jacekser, post #21297816]
What info should I provide to get help fast?
Share your decoder’s exact model, antenna type, and your postcode or town. That lets helpers match you to the correct transmitter and channels. "Make and model of decoder, type of aerial… postcode of reception location." [Elektroda, sosarek, post #21296623]
How do I manually tune MUX‑1 and MUX‑2 on my decoder?
- Open Menu > Channel > Manual Search on the decoder.
- Enter the MUX‑1, then MUX‑2 channel/frequency from the Ślęża/Wrocław table; set bandwidth 8 MHz.
- Rotate the antenna for maximum quality on the meter and save found services. ["DIPOL: Dane nadajników DVB‑T2 w Polsce"]
Which transmitter should I aim at around Wrocław, and what polarisation?
Ślęża is the primary Wrocław site. Use the official table to confirm your exact transmitter, channel numbers, and polarisation. Set polarisation exactly as listed for each MUX. Align the antenna to the shown azimuth for your address. ["Emitel: Strefa Widza — Odbiór RTV"]
Could current outages or maintenance be the reason my Polsat/TVN are gone?
Yes. Operator work can remove commercial multiplexes temporarily. A recent case left viewers without these programmes for four days in Katowice. Check the operator’s status page before changing equipment or cabling. After work ends, rescan channels. [Elektroda, MDD, post #21296702]
My antenna and cable are 20 years old—should I replace them?
Yes. Old coax, connectors, and power injectors degrade and add losses. Start by replacing the cable and the antenna amplifier power supply. Inspect outdoor joints, swap corroded parts, and reseal boots. If two different decoders show the same issue, the RF path is at fault. Do a full overhaul from the antenna to the receivers. [Elektroda, kli, #21297863]
How should I wire the decoder and TV so I don’t scan the wrong tuner?
Connect the decoder to the TV using HDMI. Select the matching HDMI input on the TV (Source/Input). Plug the antenna into the decoder’s RF IN and power any mast amplifier. Change channels with the decoder remote to confirm the TV shows the decoder. Then run the decoder’s channel search. [Elektroda, nazaspie, post #21298300]
Does the decoder brand (Skymaster/Manta) matter for this problem?
If you already receive TVP in DVB‑T2 and two different boxes behave the same, the decoder is not the cause. Focus on the antenna, amplifier, power supply, cabling, and alignment instead. Replace weak links before blaming the set‑top box. [Elektroda, kli, #21297863]
Do I need a separate antenna for MUX‑8?
MUX‑8 uses the VHF band and often vertical polarisation. Many UHF‑only antennas cannot receive it well. Check your site’s MUX‑8 parameters, then add a VHF antenna or use a wideband log‑periodic as specified. ["Emitel: Strefa Widza — Odbiór RTV"]
What if I live very close to a transmitter and reception is still unstable?
Front‑end overload can occur near high‑power sites. "There was little chance of the antenna working properly." Attenuators, filters, and different antennas can improve stability, but not always cure it. One case near Radom had 30 kW on MUX‑3 and 8.5 kW on MUX‑8. Consider cable/IPTV as a fallback. [Elektroda, irekr, post #21299679]
How can I check signal level per channel on my decoder?
Use Manual Search and enter the specific MUX channel number for your area. Most decoders show level and quality bars before saving channels. This lets you peak the antenna while watching the meter. Scan each listed MUX frequency in turn. [Elektroda, nazaspie, post #21296880]
When should I call a professional installer?
Call a pro if manual scans fail after you verify wiring, polarisation, and replace old cabling or power supplies. An installer can measure spectrum, add filters or attenuators, and align the antenna accurately. "Call in a professional." [Elektroda, Jacekser, post #21297951]
Where do I find the exact channel numbers for Ślęża?
Open the transmitter table and select the Ślęża entry for Wrocław. Note channels, frequencies, and polarisation for MUX‑1/2/3/6 and MUX‑8. Use those values for manual scanning and alignment. ["DIPOL: Dane nadajników DVB‑T2 w Polsce"]
Why do helpers insist on my postcode or exact location?
Coverage, frequencies, and polarisation change by site. Without your reception point, advice is guesswork. "Where is the reception point?" Share the postcode or town so helpers map you to the right transmitter. [Elektroda, irekr, post #21298121]
