FAQ
TL;DR: Your Samsung’s DVB‑T tuner needs 1 IEC “ANT IN” (terrestrial) socket; a threaded F‑type “SAT” wall jack won’t deliver channels. “Satellite signal for set‑top boxes” ≠ terrestrial TV. Run Auto‑tuning on AIR/terrestrial after using the correct socket. [Elektroda, headshot, post #16918251]
Why it matters: This FAQ helps apartment users who see “no signal” fix connections and choose the right DVB standard without buying the wrong hardware.
Quick Facts
- Built‑in DVB‑T means no set‑top box is required for over‑the‑air reception; use the TV’s antenna input and digital autoprogramming. [Elektroda, headshot, post #16918269]
- Threaded F‑type wall jacks are for SAT/cable paths, not the TV’s terrestrial IEC antenna input. [Elektroda, headshot, post #16918251]
- If the building has no collective antenna (AZART), you have 2 options: install your own antenna or order cable/satellite service. [Elektroda, headshot, post #16919632]
- For cable networks (e.g., UPC), select CABLE/DVB‑C mode; channels may require operator frequencies/parameters. [Elektroda, wiertacz, post #16919544]
- Ask the manager which standard is provided (DVB‑T/T2, DVB‑C, or SAT); tune only in that mode. [Elektroda, headshot, post #16919554]
How do I connect a Samsung UE43MU6172 to a building antenna for DVB‑T?
Use an IEC antenna cable from the wall’s TV/IEC socket to the TV’s ANT IN. On the TV, choose AIR/Terrestrial and run Digital Auto‑Programming. If your wall jack is only a threaded F‑type SAT output, it won’t feed DVB‑T. “On TV only SAT AIR and then digital autoprogramming” applies. [Elektroda, headshot, post #16918269]
Why do I get no channels when I screw the cable into the TV’s SAT input?
That jack expects a satellite LNB feed for a separate satellite tuner or set‑top box. It does not carry terrestrial DVB‑T from a building antenna. The wall’s threaded F‑type path is for satellite/cable, not terrestrial TV. [Elektroda, headshot, post #16918251]
Do I need a set‑top box if my Samsung has a DVB‑T tuner?
No. For over‑the‑air terrestrial signals, the built‑in tuner is enough. Connect the IEC antenna lead and run Digital Auto‑Programming on AIR/Terrestrial. A set‑top box is only needed for satellite or pay‑TV cable services. [Elektroda, headshot, post #16918269]
How do I know which DVB standard my building provides?
Ask the building manager which system is distributed: DVB‑T/T2 (terrestrial), DVB‑C (cable), or satellite. Then select that exact tuning mode on the TV. Using the wrong mode returns zero channels every time. [Elektroda, headshot, post #16919554]
What is AZART (collective antenna) in this context?
In this thread AZART means a shared, building‑wide terrestrial antenna feed. If your neighbor confirms “there is no AZART,” the wall outlet won’t deliver DVB‑T. You must use your own antenna or a pay service. [Elektroda, Gooes, post #16919615]
I only have a threaded wall outlet. Can I still get TV without a subscription?
Only if that outlet carries free DVB‑C from a cable operator. Then select CABLE/DVB‑C in tuning and enter operator parameters if asked. Otherwise, the threaded SAT path won’t deliver free DVB‑T channels. [Elektroda, wiertacz, post #16919544]
How do I tune cable channels from a provider like UPC?
Connect the wall outlet to the TV with an F‑to‑IEC lead or adapter, pick CABLE/DVB‑C, and start Auto‑Programming. If prompted, input the provider’s frequency/symbol rate from their info page. “Choose Cable TV instead of terrestrial mode.” [Elektroda, wiertacz, post #16919544]
What cable and plug types should I use for terrestrial vs satellite?
For DVB‑T, use an IEC antenna plug into ANT IN on the TV. For satellite/cable jacks, use an F‑type plug and, if feeding the TV’s IEC input, add an F‑to‑IEC adapter. The threaded SAT feed alone won’t tune DVB‑T. [Elektroda, headshot, post #16918251]
Can an indoor room antenna solve this if there’s no AZART?
Yes, if signal conditions are adequate. Place it near a window and select AIR/Terrestrial. Run Auto‑Programming. If the building blocks the signal, expect few or zero channels. Consider a balcony antenna or cable service. [Elektroda, headshot, post #16919593]
What if I still find zero channels after auto‑tuning?
Check you are in the correct mode (AIR vs CABLE), confirm the right socket, and verify the wall point is active. If only a SAT feed exists, DVB‑T will stay at 0 channels. Switch to DVB‑C or install an antenna. [Elektroda, headshot, post #16918269]
Is there a quick 3‑step setup that works for most DVB‑T cases?
- Connect IEC wall TV socket to ANT IN on the Samsung.
- On TV, select AIR/Terrestrial.
- Run Digital Auto‑Programming and save found channels. [Elektroda, headshot, post #16918269]
Will buying any decoder help if my wall jack isn’t a collective antenna?
No, not for DVB‑T. Without a building terrestrial feed, a terrestrial set‑top box still needs an antenna. Your alternatives are a balcony/outdoor antenna or a cable/satellite service with its decoder. [Elektroda, headshot, post #16919632]
What do the labels SAT, AIR, and CABLE mean on Samsung TVs?
SAT refers to satellite inputs/tuners, AIR to terrestrial DVB‑T/T2, and CABLE to DVB‑C. Pick the one matching your building feed. “On TV only SAT AIR and then digital autoprogramming” summarizes the required selection. [Elektroda, headshot, post #16918269]
Edge case: my neighbor previously used UPC on this outlet—should it work for me?
Possibly, if the outlet still carries UPC’s DVB‑C signal and your plan allows unencrypted basics. Choose CABLE/DVB‑C and scan. If the provider disabled the feed, you’ll find nothing. [Elektroda, wiertacz, post #16919544]
Can I split the wall feed to serve multiple devices?
Only if the feed is strong and correctly matched. Random splitters can attenuate signals and cause failed scans. Verify which standard the outlet carries before adding hardware. [Elektroda, Gooes, post #16919542]
Expert tip: what’s the fastest way to diagnose “no signal”?
Quote: “It is not sat… only SAT AIR and then digital autoprogramming.” Translation: identify the socket type, then scan in the matching mode. This fixes most cases in minutes. [Elektroda, headshot, post #16918269]
