Satellite dish query
Guys
I have sky HD and the dish is mounted on the garage wall.
Now a neighbour had a tree which is about 12 foot high, but its a really skinny tree with sparse branches and leaves
Said tree is maybe 20 foot away from the dish, but if the wind is blowing it around is this likely to interfere with my signal?
Tree resembles this

I'm not convinced it is the tree as for example viewing has been fine for a few months
How would I know if it is the LNB?
Last time I had viewing issues I found some instructions about powering off LNB and on again.
This did actually appear to fix it.
PS - weather in N.Ireland today is lovely - clear sky etc, however a bit windy.
I've tried calling sky, but the boy I talked to in Bangalore is a tad useless.

Really?
It went "funny" last time it it really lashed down you see and basically fixed itself?
The tree in question has been there for at least a year.
And it really lashed down here yesterday.
Prior to that it had been fine.
And put it this way, there have been no problems in the last 2 weeks and the tree can't have a lot during that time.

If its been fine and this has suddenly happened then it points to something other than the tree and you might have put your finger on it when you said it lashed down
Possibly water ingress, I'd be inclined to check the state of the cable and connector where it attaches to the LNB, if there's any sign that water has got into the cable then its probably best to replace the whole run rather than chance it finding its way into the receiver.
Alternatively it could just be that the dish has moved slightly in the bad weather, in which case putting a little pressure on an edge of it should bring the picture back, then slacken the botls and move it very gently to get the best signal in that direction.
Or, could be just a you say that the atmospherics are messing it around and it will eventually clear itself.
If you do decide to check the cable joins then have some amalgamating tape ready to reseal them.

Anything in front of a dish can affect its reception. The dish should ideally have a clear look at the satellite at all times. The tree is very likely to affect your picture.
You can mount a dish at ground level if you want, as long as it has a clear look at the satellite it will work just as well as one high on the chimney.
The reception can be affected by heavy rain and a slight movement due to strong wind can also cause a loss of the signal. If you are aligning a dish it is amazing how the slightest movement of the dish can affect the signal considerably.
Sounds like the tree is causing your problem.

I rang a local crowd and talked to him.
He asked me a couple of questions about cables and he may have hit the nail on the head.
One of the cables (the original sky cable from many many years ago) is basically flung over the roof.
The other newer sky+ cable is tacked around the side of the house.
Satellite bloke is going to call round to see if dish needs realigned or if the LNB is infact faulty.
Maybe the best thing is to replace that really old cable.
It is at least 10 years old, so maybe its fcuked.
Looking at the signal strength, input 1 (old cable) is at maximum of 90/95%
Input 2 is full in comparison, but still has quality drops on it.
Weather was very bad yesterday - torrential rain and gale force winds.
I guess you guys on the mainland will receive said weather soon.

I was going by you saying when it's windy it plays up. Which will be the tree moving.
It's hard to diagnose with out bring there with my meter. Atmospherics don't really affect satellite. Check both ends of the cable for signs of water. A LNB fault is unlikely.

It could be the cable over the roof then, not properly fastened down rubbing across the roof and cracking the cable (letting water in) this is a very common problem

Slide down - yes I think so.
Are the plug exposed - pass

We'll an update
Guy came round, plugged in a meter of some sort into the sky cables and eventually said problem is dish or LNB.
Went out and looked and immediately said tree is the problem.
So - under the cover of darkness said tree was how shall I say realigned
SkyHD fine now
And a bonus - he didn't even want a penny for the visit

I always lather the outside of aerial connectors with Vaseline. It goes semi solid after a while and resists the rain washing it off and never lets water into the conection.

Signal issues are pain to diagnose on troublesome recievers.
For example we have a dish in Spain that needs adjustment every 6 months due to being in a fringe area and seasonal drift to keep a good lock on the south beam transponder, in addition to the daily drift where signal is lost from the 2D transponder late at night (apparently it drifts by +/-50km every day). Considering that with a 1.9 metre dish, only 0.25mm of adjustment can make the difference between full signal and zero signal, one starts to appreciate that it is a bit of an art to perfect (well, when compared to using a mini dish in a strong signal area).
Having said that, the fig tree that is growing directly infront of it hasn't apperaed to affect the system's (un)reliability. Although the spiders inside the LNB feed horn have
The white Pace box's (430) current firmware is not helping as it "forgets" its default transponder is on 12.129v and any channels that maybe stored in "other channels". It also likes to say "no signal" or "technical faut" when if I put the channel's actual frequency into manual tuning its perfectly fine
Think I'll get a new box and LNB one day as its doing my fruit. Failing that, an even bigger dish. Although I don't appreciate having a minature Jodrell bank in the garden

Fitted Sky+ for my mum last weekend. No sat finder or specilist tools, lined the dish up with next doors. No signal on input 2, no matter what i did. Tried evereything, swapped cables and LNB, even called Sky, still sweet FA.
Spoke to the nieghbour, who laughed. His is looking at Hotbird he says!
I turned the dish slightly to the east (i think) and hey presto, 95% on one and two.
Live and learn.

That was only my assumption of the problem antc, i'm no Sky fitter. As, as soon as i turned the dish to Astra, both input 1 and 2 immediatly showed signal and locked. Strange but true.
As a side. Do you not have to change the 'H' and 'V' and **** about with other settings in the box to be able to view 'other' sat programs??

Made absolutly no sense to me either. Thought it would only take me a couple of hours, 2 f'ing days .
