    Hello

    Previously, I had a Sagem decoder and everything was ok even during rains and since the change to the decoder Evobox PVR produced by Cyfrowy Polsat any rain, there is no program!
    I do not know, maybe it is the fault of the converter but I doubt it is new (I do not remember the model name - it is on the roof of the block.) The neighbors have the same size of antenna (digital polsat) and converters and during heavy rains they only lightly jams.
    I checked today (no rain) the quality and signal strength of the decoder:

    Reference channels of Polsat 111:

    Signal quality = 39%
    Signal strength = 80%

    greetings

    You have low quality as without rain. Try to change the converter setting - slightly gently in its axis in one direction and the other. Really minimally and check the signal level if it is higher then farther and how lower it in the other direction.

    :) Thank you for your response

    .. but personally I can not go to the roof because the hatch is always closed. I also do not want a "professional", whom I will call me, "horns", forcing me, for example, with a small antenna dish or a bad converter.

    I will order a friend who runs a Cyfrowy Polsat point, but what should he suggest? He told me how I asked, that the bowl can be slightly turned by the wind but he attached it very strongly to me.

    It's also possible, but it looks more like the wrong angle of the converter in its axis (a large discrepancy between quality and signal strength).

    Antenna on the roof of the block, so the bank shifted or even crooked.

    The blame was the cracked lid cap clogging the converter. Rysa not very visible but the water got.

Topic summary

✨ The discussion revolves around issues faced with the Evobox PVR decoder from Cyfrowy Polsat, particularly during rainy weather, where the user experiences a complete loss of programs. The user compares this with their previous Sagem decoder, which performed adequately even in rain. Suggestions from other users include checking the alignment of the converter and antenna, as well as the possibility of a faulty converter. The user mentions that the antenna is a 70 cm dish and expresses concerns about the installation quality. A follow-up reveals that a cracked lid cap on the converter was identified as a potential issue, allowing water ingress.

FAQ

TL;DR: If your Evobox PVR loses all channels in rain, a mis-set LNB (skew) or moisture ingress is likely; one user logged 39% quality vs 80% strength, and an expert advised: "You have low quality as without rain." [Elektroda, DiZMar, post #16652041] Why it matters: This FAQ helps Evobox PVR users quickly diagnose rain-fade dropouts and talk to a technician with confidence.

Quick Facts

Why do my Evobox PVR channels vanish during rain?

Because your baseline signal quality is too low or moisture is entering the LNB. An expert noted low quality even without rain, which rain then worsens. Correcting LNB skew or replacing a wet/damaged LNB restores margin. "You have low quality as without rain." [Elektroda, DiZMar, post #16652041]

What does 39% quality and 80% strength actually mean?

It means the tuner sees a strong carrier but poor data integrity. In the thread, that 39% quality on a clear day left no reserve for weather. Aim to raise quality first via alignment or LNB work. Strength alone won’t prevent rain fade. [Elektroda, fotosing, post #16652029]

How do I adjust LNB skew to fix rain fade?

Skew is the LNB’s rotation. Small tweaks can sharply raise quality.
  1. Rotate the LNB a few millimeters on its axis.
  2. Watch Quality; keep the direction that increases it.
  3. Lock the LNB when Quality peaks, then recheck several channels. "Try to change the converter setting – slightly." [Elektroda, DiZMar, post #16652041]

Could a cracked LNB cap cause total loss in rain?

Yes. In this case, a hairline crack in the LNB’s plastic cap let water into the feed, causing outages in rain. Replacing the LNB or cap fixed it. Look closely; cracks can be subtle yet disastrous. [Elektroda, fotosing, post #16778483]

Is a 70 cm dish enough for Cyfrowy Polsat?

Yes, when aligned correctly. A 70 cm dish was confirmed as standard in the thread. If rain still wipes channels, focus on LNB skew, mount rigidity, and water ingress before upsizing the dish. [Elektroda, 1098678, post #16652560]

Do I need an SCR LNB with Evobox PVR?

Confirm your LNB type and model for the installer. A participant asked whether the setup used an SCR LNB, so your technician may need that detail to validate compatibility and wiring. Bring the exact model name. [Elektroda, 1098678, post #16652089]

Can wind shift the dish enough to cause these issues?

It can. Even a strong mount can move slightly, degrading quality. One user suspected wind had turned the dish a bit. Verify mast plumb, bracket torque, and dish azimuth/elevation during service. [Elektroda, fotosing, post #16652057]

How can I tell if my dish is misaligned or crooked?

Look for inconsistent Quality that worsens in rain and improves with tiny LNB or dish adjustments. A pro on the thread flagged an antenna on a roof as likely shifted or crooked. Re-aiming typically resolves it. [Elektroda, andpol 33, post #16652126]

What should I tell a technician if I can’t access the roof?

Share your Quality/Strength readings, LNB model, dish size, and that symptoms appear in rain. Ask them to check LNB skew, dish alignment, mount rigidity, and LNB cap integrity. Emphasize baseline low quality. [Elektroda, DiZMar, post #16652041]

Why do my neighbors only get light glitches while I lose everything?

Your baseline quality is weaker. The thread shows similar hardware nearby working with only slight jamming in heavy rain. That points to your alignment or LNB condition rather than a shared broadcast issue. [Elektroda, fotosing, post #16652029]

Is there a quick test I can do before calling support?

Check Quality on a clear day. If it sits near 39% as reported in the thread, you lack weather margin. Note all readings, then schedule alignment and LNB inspection. Keep the dish size handy (e.g., 70 cm). [Elektroda, fotosing, post #16652029]

What was the single fix that solved the thread’s issue?

Replacing the LNB (or its cracked front cap) ended the rain-time channel loss. Water had entered through a barely visible crack. After swap, service returned to normal. [Elektroda, fotosing, post #16778483]
