If they get weaker, turn in the opposite direction. Keep turning one quarter turn at a time until the signal peaks and starts to go back down. Then turn back one quarter turn. Proceed to the next direction until the dish is completely peaked. Finally, tighten everything down to minimize any movement from the dish. What about an amplifier or a larger dish? About the Author.

Some other things you may want to check for include: Cable Corrosion: Sometimes, the cables or cable ends may be slightly corroded. Exposure to the weather can cause problems, but when a cable is already corroded, further exposure can make things worse. The satellite dish captures a clear signal but it then gets distorted as it travels down the cable. Obstruction: Anything from animals, to trees, to other debris could be keeping signals from transferring.
Dish Alignment: A strong wind can move the satellite dish. A poorly installed dish or a dish that has been dislodged from its original location may cause a poor satellite TV signal. How to Stop Your Satellite from Going out in the Rain With a good satellite service provider, rain fade should only decrease your TV quality for a short period of time.
However, there are still a few methods of decreasing the chances of rain fade from taking place: Get an Antenna: Rain fade can be lessened or even eliminated by the addition of an antenna. Get Better Aim: Simply spending a little time adjusting your dish in a way that is less obstructed and more in line with a signal is the best way to get better quality signals.
Decide on a direction. When installing a satellite TV dish, professionals will consider compass heading, dish elevation, dish tilt, and more to determine the perfect alignment. Adjust the screws. There are small screws on the mechanism to help move it into the correct position. As satellite TV uses very high frequencies with very small wavelengths within the Ku Band This effect is increased further with services such as satellite broadband which use higher frequencies still within the Ka band.
Within the section I offer some suggestions on how to remove rain-fade from your satellite signal. You may find that despite having a satellite signal that works the majority of the time that the dish is slightly offline and improvements can be made by altering the alignment.
This can be because it was never aligned properly when installed or it has moved slightly, this can happen in high wind especially when the dish is old and rusty. This is not as easy task without the correct equipment so you may need the assistance of a satellite engineer with a decent TV spectrum analyser or alignment tool, even some of the cheaper satellite alignment tools are not easy to use when aligning a dish for peak reception.
If choose to do this yourself you may find that inside the settings of your satellite TV or receiver that you have some signal readings that you can strive to improve when playing around with your satellite dish alignment. This is often overlooked, even sometimes by people within the trade.
This needs to be set correct so that the dish can differentiate between horizontally and vertically polarised signals. As the satellites for satellite TV are in geo-stationary orbit and rotate around the equator, if you could see all the different satellites in their orbital positions when looking south in the northern hemisphere or north in the southern hemisphere, these would form an arc in the sky.
With the highest point being due south northern hemisphere and the further east or west you deviate the lower this would be. Now if you can imagine the effect this would have on the satellite signal polarisations, they would gradually become more diagonal the further off due south you get and you must make an alteration on the LNB adjustment to be able to maximise the signal quality.
It can make a very big difference to your reception if this has been set wrong. An example of this using Dishpointer for the Astra 2 satellites situated at Changing your satellite LNB for a better quality model could see some improvements to your satellite signal which can reduce the effect of rain-fade. Depending which satellites and countries TV you wish to receive and your location that you wish to receive it will effect what size satellite dish you require. It may not make you popular with the wife but a larger satellite dish can help improve your satellite signal in rain.
For example in the South of the UK a Zone 1 43cm mini-dish would normally offer reliable reception for Sky and Freesat TV, but on occasion when customers request a larger dish to improve the signal quality, I install 60cm Zone 2 satellite dish which normally only would be installed North UK and Scotland.
It could be that water in penetrating the coax cable that connects between your LNB and satellite receiver and causing a cable short which will stop the DC voltage flowing from the satellite receiver to your LNB causing no satellite signal.
The most common reason for this would be that the LNB rainwater cover has not been pulled down the protect the F connectors or that the cables have not been weatherproofed correctly. You must pull down the rainwater where you have an LNB that has one and you may want to consider a smear of silicone grease around the connection, or a wrap of self-amalgamating tape not easy to get around multiple connectors or weatherproof F connectors.
