sky install on a pole!

    Hi, had sky out a few months back to try and install their system. They failed and said some trees at the side of my house were blocking reception and they couldnt do it.
    Since i have made another appointment for them to come out, and need to get setup with a pole in the back of the garden where i'm pretty sure they will get reception.
    Any idea how tall the pole needs to be, where i can get on, and how best to fix it, should i leave it mobile till sky come so they can find the perfect spot, then fix it? put it in a bucket of cement, so it would be a bit mobile for adjustments, or just have the pole and get them to fix it to the back garden wall?

    Any advice would be greatly appreciated.
    Thanks.

    Height is irrelevant- you need a clear view with the horizon- regardless of what height you have to go to achieve this. You also need the pole to be sufficiently anchored to withstand high wind- note: if it moves at all, you can be virtually guaranteed a degraded signal.

    You are joking about a bucket of cement?

    OK, so how can i find the perfect postion to anchor the pole?

    Trigonometry, or a protractor and a bit of string. Assuming the Astra-2 satellite cluster is at an elevation of at least 20 degrees above the horizon at your location, make sure the dish has a clear view of that patch of sky in the relevant direction.

    South/south east.
    Forget Sky,go to a local independent installer and get a popper survey done.
    Check your local paper small ad's.

    See http://www.satcure.co.uk/tech/satmeter.htm
    Scroll down to "Find out which way to point your dish!"
    Type in blanchardstown.

    "Height is irrelevant", ehh...no its not! If a tree is 4 metres high and you install the dish on the pole at 4 metres up, its going to get a reception coz the angle the dish is facing will clear the top of the trees...however, if a tree is 4 metres high and you can only install the dish 3 metres up on the pole, you aren't gonna get a signal...therefore HEIGHT IS NOT IRRELEVANT!

    Wouldn't wind blowing the dish on the pole cause frequent loss of signal?

    Depends on how well its anchored- but it would be a definite issue (hence- putting it in a bucket of cement is hardly a good idea).

    Just read these postings.

    I do have a dish mounted on a 5 foot fencing post sunk approx 15 inches in cement. The post is also supported by a stay attached to a low garden wall. The dish is very steady and I receive 90% to 100% constant strength and quality. This arrangement is situated back about 25 metres from the rear of my house but does 'look' through a gap to the south between trees and the house.

    As previous threads have pointed out everything depends on circumstances existing at the site in question.

    Other concerns about having a dish at such a level involve hitting it with say a lawnmower, hedge clippers or just people enjoying the garden and knocking into the dish by accident.
