No Signal on Astra 19.2 or 28

    Following previous advice I replaced Diseqc and when that did not work 1 of the 2 LSPs. .... No better. The remote calls up whatever channel I want on the screen followed by "No Signal" in every case. What could be the cause ? I also moved dish a little hoping I would get at least some signal.. No Luck! Any suggestions would be welcome. I live south Dublin..

    A satellite signal meter would help you re-position the dish. Even a slight misalignment will

    cause complete loss of signal. Basic meter costs around €15.

    What receiver do you have? Have you setup the diseqc with the correct ports for each dish? Can you try and use the receivers signal finder or add a new transponder to see if there is any signal strength and quality? Do you have any channels on either 19.2 or 28.2?

    I have lost all vertical polarity channels on my 28.2 feed which comes through a dvbt satellite combiner. All Horizontal polarity channels are fine for some reason. New combiner needed maybe?

    Anyone any advice?

    Get a signal meter. The sweet spot is very small and measured in 1mm movements with a 80cm dish and the difference between signal and none is not much bigger.

    What happens if you bypass the combiner for satellite ??

    Water getting into an LNB can cause failure of one polarization only with the other still working (for now)

    That's been the problem with my FTA satellite setup at the moment. Water going into the dish may have caused my signal to completely fail even though it started to go bad since over a year ago.

    My installer told me today that he had been very busy with lots of recent callouts to jobs with fixing people's TV setup's after Storm Barra hit the country last week. He said that I will be getting sorted sometime early next week. I'm happy with that outcome now since it's coming up to Christmas.

    I've encountered another problem with my current Satellite dish installation. I live in an area of South Dublin that has new apartments getting built across the road from the house. The developers had workmen on the site since April of this year.

    The satellite dish installer had said to me last night that one of the main reason that I lost the signal to the channels was the cranes that are on the building site are causing a signal obstruction. As a solution to the issue a proposed remedy given to me to place the dish on the roof, and maybe the aerial as well, on the roof up near the chimney.

    A new bracket would have be installed on the roof to hold the dish & aerial together. He did say to me that he will come over to the house with his colleagues next week to install the new setup for a cost of €300.

    However; he has said to me that if that problem doesn't work at all; he won't charge me for the job. He did say as an alternative would be to get the channels from VM instead.

    However there is another thing that I haven't even told him yet when he came over to the house to have a chat about it. A lot of my nearest neighbours have satellite dishes installed for Sky in their own back gardens including the row of houses located right across from my front door.

    My elderly next door neighbour however has VM channels & broadband installed in her house.

    I also have 2 neighbours living who live right beside her. They have a dish and aerial setup right in front of their chimney on their house which apparently gives them both a good TV signal.

    Is their a chance for me here that I would get a much stronger signal for my new FTA Satellite/Saorview setup for my house from now on or would it be much weaker as the cranes are still there working on the building site across the road.

    The other houses near me appear to have no complaints about their own TV reception with the dishes on their houses if I have to move up the dish & aerial near the chimney.

    Satellite dishes have to have a clear view of an exact spot in the sky. It's possible that you are just very unlucky with the cranes. Your neighbours would be pointing at a slightly different angle and could well be avoiding the cranes. Think of it like looking at a star. If a tree or something blocks your view you simply move a few metres either side to see it again. The installer would have a meter with him that will tell soon enough if there is a good signal up at the chimney. The only thing I'd be worried about is when you say they are building apartments. If they are very high they could ruin your chances once built.

    The current issue with the dish is with how it's aligned from the house. It's currently situated at the side of the house right beside the aerial.

    The dish is aligned at a south east angle towards the lower end of the UK maybe hitting below the south of Wales/the top part of SW England.

    If it's being placed on the chimney later this week. It maybe pointed further eastwards towards the East Midlands of the UK or maybe within the lower part of Wales but I'm not sure at this point.

    However; the aerial for Saorview is pointed at a south west angle towards Three Rock.

    My location is in Blackrock; Co.Dublin.

    Both the dish & aerial are located on the midway point on the side of the house which is between the top & bottom floor. There is also a small laneway underneath both of them which goes into the back garden.

    It's probably the main reason why the reception of the dish is having issues with maintaining it's signal. It's height is maybe aligned at a level that is way too low for it to receive any sort of reliable signal being fed into the house.

    Increasing the height of both of them could be the only solution at present that can allow the satellite signal to come back into the house by becoming reliable again. That being said; the aerial for Saorview is having a very good signal at the moment. It's shows no sign of being degraded for now which I presume is a good sign at the moment.

    I had a look at to have a look the obstruction earlier tonight. It said it had a distance of 49.9 metres & a height of 19.6 metres. Now that tells me that the cranes could be the main culprit in blocking the signal of the dish.

    Another problem coming from the apartments is that the scaffolding could be at fault as well that is currently being used for building the apartments.

    The highest apartments block on the new site is being built at 5 storeys. The 2 other blocks beside are being built at 4 storeys each.

    If that's referring to the satellite dish doesn't matter where on the building it is, the direction its pointed in will have remain the exact same within a very tight margin.
