Effectiveness of Dedicated Converter Cover Against Signal Loss During Heavy Rainfall

Hello
I have a problem with signal loss during heavy rainfall, most often during spring storms. I have a question whether the dedicated cover for the converter that is available at Allegro auctions will improve this situation or is it just bajer and better to invest in a larger canopy?

Write something more about the installation because the cover is a secondary matter.

The cover is a gadget that can partially shield you from the snow. There are many other factors that affect the stable reception in difficult weather conditions. Sometimes you can not do anything, because ...

Advocates, the author asked for a visor!
Unnecessary, even harmful.

Not harmful at all and you do not know what you're writing about.
A roof is not required and as it wants to improve reception it is necessary to ask about the installation it has.

My antenna is a dozen-year-old steel 70cm, mounted on a flat roof, nothing covers the sky. Practically all the time it works, only during rainfall loses the signal.

And I would not advise you to move anything because sometimes you can write in a moment that I do not receive anything. The antenna is a bit small, but a little bigger dish will only slightly reduce the impact of rain on the pickup. It is not possible to eliminate the impact of precipitation on the reception. The larger bowl is just a matter of how strong the rain will be the lack of reception.

If the shield is to interfere, it is probably the one I saw and took a picture, D



or such a roof; D



And seriously, if someone did not apply it once and did measurements then he should not speak. And what if we get 10-15% of the signal with weak satellites using the canopy? And what does he protect us from? And I'm not thinking about antennas in the order of 90cm!



Dry statements do not contribute because everyone can write a colleague @ mihal2002
Put your statements on facts and not on guesses.

And I am sending you back to the TechniSat Multytenne kit.

And what does this have to do with the topic? Did he write that snow bother him? Like a bull, he's asking for rain. And what will this roof help in the rain? The reflected sun will make a "clean tunnel from the converter to the satellite"?
I like choosing a family.

The roof for the converter during the rain is to help, and the water flowing around the entire bowl (the antenna mirror) does not bother .
After all, in a drop of water flowing down the antenna mirror, the signal "melts".
No visors here will give anything, because what gives protection to the converter, when in front of his "nose" on a rainy day "passes" 20 liters of water on the mirror of the antenna.

Larger antenna and set it more precisely (the signal may also disappear, but much later, or not at all and during the rain, the antenna will work as it should).

Most of the "casings" on the converter are bajer. With a standard offset, the canopy obscures part of the original signal.
No professional bowl has similar solutions. The only thing that is used is heating the front part of the waveguide around its circumference and heating the canopy itself, especially its lower part. I will not mention that automation will be useful for this.
Returning, however, to the usual "Kowalski" is a good quality tin 85 and a converter of both brands, eg. Inverto gives advice in every rain except for several kilometers of storm clouds ...

He had some nonsense about it. A better rain at such a bowl is the lack of reception.

I hear it on average 3 times a day from my potential future clients for the last 15 years or so.
And from individual customers with decent, well-matched and properly tuned equipment, I have peace for a minimum of 2 years warranty.
Of course I am talking about a relative diameter of 85cm (only no Corab, old Mabo, Triax or Televes). But neither for some cosmic money.

There is no problem to get MER from this diameter of 14-14.5 dB (in relatively good propagation conditions, i.e. slight cloudiness) for most of the transponder platforms significant for Polish even for 8PSK modulation. There is no chance that the rain of the moderate climatic zone will disturb the correctness of demodulation. Well, unless you give drops to the diameter of more than 1cm.
Only storm clouds (often exceeding 10km, and hail in the upper layers above 1cm) and snowstorms (but such specific ones) that will be in the reception line can effectively disrupt the signal even to bowls above 2 meters.

98% of the problems of simple installation are the incompetent assembly and apparent tuning, then poor quality of sheet metal, wrong converters (and indirectly waveguides) and lack of maintenance
I will add that I have a few hotels, centers, dpsów, with 85-tkami where they ate me for breakfast in the event of even disruptions in the rainy season ...

Certainly not any cup morch or converter.

I wish you the correct pickup.
