Improving Hotbird Satellite Dish Signal Quality for TVN Channels - 80cm, 4 Decoders

Question

Hello, my friend has a problem with the antenna installation on Hotbird, namely the signal quality is low, which causes TVN channels to clip. However, the signal strength is good. 80 cm antenna, converter for 4 decoders, the same on each.
What will help here? Replacing the coaxial coil, converter, do you need to adjust the antenna?

Hello, I have an identical problem: I recently noticed that the signal strength = 68%, quality 67% and the decoder claims that there is no signal at the sat1 input, if left alone after 5-10 minutes it will eventually catch the signal and work properly for up to an hour. Regards

Poorly positioned antenna, crooked antenna, poor converter.

For Quad 90 and very precise positioning of the antenna and LNB rotation.

Due to frequent strong winds, the antenna may have been slightly moved, resulting in signal loss, and a slight deviation of the satellite dish is enough to cause the signal quality to deteriorate rapidly. It is also worth checking the cable ends at the converter for tarnishing, is the plug protected against moisture with a rubber band?

The strength is good, so the cable probably falls off.

Provide photos of the installation, location, etc. because it`s just a guessing game.

Each decoder has differently written software. Premiumbox wifi shows the lowest quality (on average 20-25% less and often uneven on individual inputs). The most reliable readings were provided by N-ki decoders (turbo, media, soap boxes). The best number is that you can`t get 50% on premiumbox and the original 80, and on the hotline they always tell you that it must be at least 50%.

These are not differences in head sensitivity - these are differences in the scaling of voltage changes corresponding to changes in head gain. Every programmer scales what he sees... Of course, there are also variations in the parameters of the heads themselves, but this is usually insignificant or irrelevant to the programmers` ideas...

@andpol 33 possibly a bad coaxial cable.

A friend of mine had a SAT installer, he corrected the satellite positioning and, interestingly, he set the quality on the measuring device to 80%, and on the decoder it shows 48%. I know that each decoder has a different sensitive head, but how could there be such differences?
