    Good day. Some time ago I bought a room antenna for a TV with a DVB-T receiver. I catch 23 channels there, but that's enough for me. The problem arose when moving house, where I can't put this system anywhere, because I have a problem with reception. I know that a room antenna is not the best solution, but for now I can only afford such a thing (I live in a dorm).

    The problem is that the antenna has a very short cable and I have no room for maneuver. I would like to extend it. Is there any way I read something about "F" connectors, but I don't know if it will work :) Please answer, I will be grateful :)

    will everything be fine? won't you fuck the picture? :P


    As for the 2nd method, that's what I thought, but I don't know if it's better to buy this antenna cable than to play in cutting insulation, etc. :P

    The second method is more reliable.

    The ready ones are unfortunately trash. You can sometimes be surprised, which made the reception worse.

    I have already ordered this plug / socket cable. If it doesn't run fast, can I cut it and buy these "f-kes" for this cable?

    It would be cheaper to buy everything on the spot and turn it, but it should be too late, it should be Ok, though in a worse and probably more expensive version :D

    No. This cable is usually the culprit. Buy a coaxial cable.
    F-ks are bought according to the cable.

    Okay, I understand that the mean in each concentric is different. Approx. So how does such a coaxial cable work. Normally I connect it to the TV and in the end I have this "tip"? :P Does it work better than a room antenna? I don't know anything about it, but I know that once a homie probably had one connected to the TV and tied around a radiator and it worked :P

    Are you writing about extending the cable to the room antenna, then what tip should work better than the antenna?

    This cable does NOT WORK better according to your reasoning, it doesn't receive a signal! It is only a medium that transmits the signal received by the antenna to the TV. In contrast, a bad concentrator can strongly weaken the signal reaching the TV. Hence, colleagues advise to buy a good cable and "earn" it correctly, i.e. put on the plugs. You must be careful that the braid does not touch the middle wire. On the net you will find many instructions on how to set up "F-ki". In order for the cable to match TV and antenna cable, you must attach the adapters shown in the second photo of post No. 3

Topic summary

✨ The discussion revolves around extending a room antenna cable for a DVB-T receiver to improve TV reception in a dorm setup. The user faces challenges due to a short cable length and poor reception after moving. Suggestions include using an ordinary antenna cable with F connectors, which can be purchased or assembled. The reliability of DIY methods is emphasized, with advice to avoid pre-made cables that may degrade signal quality. Proper installation of coaxial cables and connectors is crucial, as a poor connection can weaken the signal. Users share insights on the importance of using quality components and provide guidance on how to connect the cables correctly.

FAQ

TL;DR: For better DVB-T reception in a dorm, build a coax extension: 2 F connectors + 1 plug, and “You can do it yourself.” [Elektroda, LeDy, post #16852282]

Why it matters: A simple DIY extension lets you place the indoor antenna where signal is strongest without buying new gear.

Quick Facts

How do I extend a short room antenna cable for my DVB‑T TV?

Use a standard TV antenna (coax) cable as an extension between the antenna and TV. This adds length so you can place the antenna in a better spot. Keep runs tidy and avoid sharp bends. Hand‑tighten connectors to ensure a solid shield connection. [Elektroda, Adamcyn, post #16852256]

Which is better: a ready‑made extension or a DIY F‑connector cable?

Build your own with proper coax and F connectors. “The second method is more reliable.” This approach reduces failures from low‑quality molded jumpers and lets you choose decent cable. It also simplifies repairs if a plug fails. [Elektroda, marqqv, post #16852312]

What exact parts do I need to make the extension?

Buy one length of TV coax cable, two F connectors sized for that cable, and one F coupler or plug to join sections. This is the simple, proven shopping list shown in the thread photos. [Elektroda, LeDy, post #16852282]

Will extending the cable hurt picture quality?

Quality depends on the cable and terminations. A poor coax or badly fitted plug can severely weaken the signal arriving at your TV. Keep the shield intact, avoid kinks, and fit connectors correctly to prevent added loss. [Elektroda, zworys, post #16868821]

Can I cut a pre‑made plug/socket cable and add F connectors to it?

Avoid this. Those thin pre‑made jumpers are often the root cause of reception issues. Use a proper TV coax instead, and buy F connectors that match that cable. This prevents recurring noise and breakage. [Elektroda, LeDy, post #16853296]

What does a coaxial cable actually do in this setup?

Coax does not receive TV on its own; it only carries the signal that the antenna captures to your TV. A bad coax can reduce the signal substantially before it reaches the tuner, causing pixelation or dropouts. [Elektroda, zworys, post #16868821]

What is an F connector?

An F connector is a threaded RF plug used to terminate coax. It clamps onto the cable’s shield and presents the center conductor as the signal pin. It’s common on TV and set‑top gear and easy to install with simple tools. [Elektroda, LeDy, post #16852282]

How do I fit F connectors without shorting the cable?

Strip the coax cleanly; fold back the braid; trim the dielectric; screw on the F so the center conductor protrudes. Ensure no braid strands touch the center wire, or the signal will fail. “Be careful that the braid does not touch the middle wire.” [Elektroda, zworys, post #16868821]
  1. Strip and fan back braid.
  2. Trim dielectric; expose center wire.
  3. Screw on F; inspect for stray strands.

My dorm limits antenna placement—what’s the best quick improvement?

Build the DIY F‑connector extension and move the antenna to a window or higher shelf. The more reliable DIY lead reduces added faults versus cheap jumpers and lets you experiment with placement until reception stabilizes. [Elektroda, marqqv, post #16852312]

Does a coax cable by itself work as an antenna?

No. The coax is only a transmission line. It does not improve reception when used alone. You still need the indoor antenna to capture the signal, then the coax delivers it to the TV input cleanly. [Elektroda, zworys, post #16868821]

What is DVB‑T here, in plain terms?

DVB‑T is over‑the‑air digital TV received by your room antenna and decoded by your TV’s tuner. In the thread, the user reports receiving 23 channels with a working indoor setup, confirming a typical DVB‑T use case. [Elektroda, 69guziec, post #16852244]

Which F‑connector size should I buy?

Choose F connectors matched to your specific coax cable diameter and build. A mismatched connector leads to loose fit, shielding gaps, and intermittent reception. “F‑ks are bought according to the cable.” [Elektroda, LeDy, post #16853296]

Can wrapping the cable around a radiator boost signal?

Skip that. The cable is not the antenna, and metal objects can detune or short the system. Focus on a proper antenna position and a sound coax run with clean terminations for stable reception. [Elektroda, zworys, post #16868821]

Why did my picture get worse after using a cheap extension?

Low‑grade ready‑made jumpers often use thin, lossy cable and poor connectors. They can introduce noise and signal loss that cause breakup. Users in the thread report worse reception from such leads. Build your own for reliability. [Elektroda, LeDy, post #16852367]

I already ordered a pre‑made extension—what’s the fastest fix?

Use it as a stopgap if delivery is imminent, but expect lower reliability and higher cost than DIY. Replace with proper coax and matched F connectors when possible for a stable setup. [Elektroda, marqqv, post #16853278]
