Bought this along with a DIY Dish & Cable kit from a different seller on amazon.
Once I had installed the dish & lined up the dish in a similar direction to the neighbour's dish, I used this sat finder to make minor horizontal & vertical adjustments to improve the reception.
Simply attach the small lead that comes with the sat finder to the dish, then switch on your freeview receiver & connect the sat finder to the receiver. Make sure that the display is lit up (it should be as it draws power from your free sat receiver), Turn the dial fully up to 6, slowly move the dish horizontal, backwards & forwards until you get a strong signal - once you hit 10 on the needle, turn down the dial to 4 & move again until finally you cannot improve on strength. Then repeat the process, moving the dish vertically & when you hit 10 again on the needle, turn the dial down to 2 to fine tune the signal even further. Once you have a really strong signal that you are happy with, tighten up the bolts & check your TV screen for a picture & also signal strength. It really is that easy with a satfinder!
If you are installing a dish yourself, I would recommend you get one of these. Sure its not as good as the professionals use - those tell you exactly which satellite you are pointed at but cost £80+ Thats the only drawback with this sat finder - it is possible to pick up another satellite as there is one pretty close to the Astra satellite. So just bear that in mind if you find you are only picking up german channels - you are pointed at the wrong satellite!!!
When you consider to get a professional to fit a free to air satellite system will cost you £200+ it is worth considering doing it yourself.
For me it cost £31 to install it myself:
£6 for sat finder,
£25 for a satellite dish, cables & clips for around £25
£0 for the free to air receiver - used my old sky digital receiver, but you can buy one on Amazon for £29
£5 for a 10mm thick drill bit - 600mm long (to drill hole through the wall for the cable - 10mm thickness is enough for the "shotgun" double barrel cable)
Well worth the money
