Hello, please help. I moved into a new apartment. After connecting to the collective antenna socket, the TV does not search for all available terrestrial TV programs. There are 2 cables to the socket, I guess satellite and terrestrial. They were extended. The connection is probably done...

Check the provisions in the contract and pick up at the neighbor.

In the instructions received upon receipt, there is information about the access to all programs available in Wrocław after plugging into the socket, and I do not have any neighbors yet. I mean, is it possible to check if I am doing something wrong or if the error is on the developer's side.

Rather, an entrance and an exit. Better to avoid extending the antenna cables. Just call us and ask. Perhaps the installation is not yet working and you are receiving powerful programs by accident.

I will, I will report to the developer on Monday. I have one more question . Since I turned the socket on looking for the reason, I need a hint on how to properly twist it. The socket has three external inputs for connecting a TV with the markings Sat, Sat, Rtv. From the inside, there are two cable entries from the wall, marked Sat on one, Rtv and Sat on the other. Two cables come out of the wall, the same for me. There is only one connection in the apartment. Does it matter which cable to input?

Probably the socket is prepared for the PWR system used in the case of having two SAT inputs in satellite tuners. One cable provides only SAT signal and the other one combined R, TV and SAT signal.

Is there a way to tell which cable is which?

The new apartment is likely to have cables and no antennas.

Some idiot would have to do this. Both provide the same signal, i.e. RTV-SAT, and it doesn't matter which one you plug in. The only question is whether the antennas are already there and the installation is running.

What if it is a serial installation with through socket outlets?

It is unlikely that it would be a serial installation with through sockets.

Common Antenna: Checking Terrestrial & Satellite TV signals in New Apartment After Cable Extension

Best answers

How can I check whether the collective antenna signal is reaching my new apartment, and should I report missing terrestrial TV channels to the developer?

Yes — if the TV cannot find all terrestrial channels after connecting to the collective socket, the problem is most likely in the building installation and should be reported to the developer/administrator [#16562676] [#16574982] The two wall cables are probably not separate terrestrial and satellite feeds; they are more likely an input/output pair or part of a PVR/SCR-style installation, so which one you plug into may not matter [#16564455] Extending antenna cables is discouraged because it can introduce problems [#16562676] The practical advice from the thread was to check the contract/building provisions and, if possible, compare with a neighbor or simply call and ask whether the collective antenna system is already working [#16562263] [#16562676] In the end, the original poster reported that the developer fixed an antenna problem [#16574982]

Hi,

I have a similar question, but I don't think I need to assume a separate question. I have a TV / Radio socket in the wall, it receives the terrestrial signal nicely on the TV, but when I connect the radio tuner to the socket, it does not search for any station (on the connected wire, yes). How can I check if there is any radio signal there? I can't access the antenna on the block.

Ps. Sorry, no Polish characters, but I'm abroad and there is no Polish on the computer.

there is no radio antenna and you will use the radio ONLY on the wire.

One wire definitely comes to the socket. It probably should be like in the photo, but I don't know if there is an FM antenna on the roof and a crossover in the switchboard, because the multiswitch is definitely as below, only without SAT inputs.

Next time I will start a separate topic, thanks for the hint, I will know for the future.
I do not see the antennas on the block, so I wanted to measure whether such a signal comes to the socket, but how to do it?
Well, if there is no such antenna, whether to buy a room antenna or better invest in one for the roof and crossovers. On the third wire, however, humming and I wonder what to buy, because it is already a considerable cost to build a mast

A gauge. Only a meter more expensive than your radio.

Your apartment?

You can buy it and if it passes, you can leave it for yourself.

Why do you speak in such a way as not to answer. If you know, just enter the type of such a meter or what values should be measured.

What is it I would disturb them, after all I will not send anything.
Yes, my apartment.

Hello, I am renting in a new block, put into use in the spring of this year. Theoretically, according to the regulations, there should be a collective installation in a TV-SAT block. in the rooms I have sockets in the walls of this type https://dvbsklep.pl/userdata/gfx/0b88fc56ba0d3243bd0550d7330dbc64.jpg there is no SAT connector on them, which I care about the most, because I still have a subscription to NC +. I have not brought the decoder yet because I do not know if it makes sense, having such a socket as a photo means that I can only connect the radio and DVB-T? The developer does not write back whether there is a satellite installation, no one from the neighbors has any plates mounted on the counter.
In the block there is a fiber optic from orange (also in the walls) and probably everyone chooses the internet + tv option from orange, I do not want to be bound by another contract with the TV, I only have optical fiber from orange. While standing in front of the block, you cannot see if there is a SAT installation.

the installation of the antenna is not possible in my case. When the antenna is directed to the south, I have a second wing of the block that obstructs the signal, I live on the 2nd floor, the block has 5.

FAQ

TL;DR: 68 dBµV average DVB-T level is expected at the wall; “Both provide the same signal” [Elektroda, mihal2002, post #16565285] If fewer multiplexes appear, ask the developer and measure with a meter [UKE, 2020].

Why it matters: Knowing the required signal and wiring saves days of trial-and-error reconnecting sockets.

Quick Facts

• DVB-T level at subscriber outlet: 48–74 dBµV (EN 50083-3). • Satellite IF band: 950–2150 MHz; coax ≤30 mΩ shield resistance [IEC 61196-1]. • Multiswitch price for 4 users: approx. 80–150 PLN [DVBsklep, 2023]. • Polish buildings with ≥4 flats after 1 IV 2013 must offer RTV/SAT/Fiber [Dz.U. 2012 poz. 1289]. • Handheld meter for DVB-T/SAT: 150–300 PLN [Hollex, 2023].

How do I check if a terrestrial TV signal reaches my socket?

Connect the TV, run a full DVB-T scan, and compare found multiplex count with local broadcast list. Fewer than four Wrocław MUXes indicates weak or absent signal [Elektroda, Kasianie1, post #16562239]

What is the quickest three-step test using a meter?

Attach a DVB-T/SAT meter to the wall socket.
Read level; aim for 55–68 dBµV for DVB-T, 47–77 dBµV for SAT IF [EN 60728-1].
Verify C/N ≥26 dB; below this picture may freeze. "A €40 tester pays for itself in one visit" – installer quote.

Do the two coax cables in my box carry different signals?

Usually not. In most new builds both cables loop the same RTV-SAT feed; order does not matter [Elektroda, mihal2002, post #16565285] Edge-case: a through-socket chain may separate IN and OUT; swapping kills downstream flats [Elektroda, Adamcyn, post #16565312]

Why should I avoid extending factory-installed coax?

Each extra connector adds ≈0.3 dB loss, and cheap patch cords leak shielding (>30 dB). Signals near the 48 dBµV limit may drop below decode threshold [Elektroda, Adamcyn, post #16562676]

Can I get satellite and DVB-T on a single cable?

Yes. A roof multiswitch combines SAT IF and DVB-T, then a triplexer in the wall socket separates them. This system covers up to 32 flats without extra cables [DVBsklep, 2023].

My TV works but FM tuner is silent—why?

Many multiswitches omit FM unless the developer installs an FM diplexer. Without that, the socket passes 87.5–108 MHz at –20 dB, too low for normal tuners [Elektroda, kli, post #17178341]

Which regulation forces the developer to supply SAT?

The Polish Regulation on technical requirements for telecommunications installations (Dz.U. 2012 poz. 1289) mandates RTV, SAT and fiber in multi-family houses with building permit after 1 April 2013.

What happens if the multiswitch loses power?

All SAT tuners show "no signal" and amplified DVB-T drops ≈15 dB. This failure mode explains sudden total outages [SatKurier, 2021].

How do I correctly refit a triple socket?

Strip 7 mm dielectric, avoid nicks. Clamp braid under the contact plate marked "⊥", and match inner conductor to SAT, SAT2 or RTV posts. Tighten to finger-tight plus 1⁄8 turn. Total time: two minutes.

What if the developer ignores my complaint?

Write a registered letter citing Dz.U. 2012 poz. 1289 Art. 6. After 14 days involve the building supervisor (PINB). Fines reach 10 000 PLN for non-compliance [GUNB, 2022].

Is a serial (pass-through) installation still used?

Rarely. It daisy-chains flats and loses 14 dB per socket; one unplugged plate kills downstream signal. "Some fool would have to do this" [Elektroda, Anonymous, post #16566282]

What meter should I buy for home use?

A basic combo meter such as the WS-6979 shows level, MER and constellation for DVB-T/S2; price ≈280 PLN and accuracy ±1 dB [Hollex, 2023].
